I'm hoping the SR2 mod interface, when it eventually arrives, has some more advanced package management.
I remember every time KSP changed versions, a bunch of my mods would be subtly broken. But each would have to be updated manually.
I never developed mods for KSP, but I would hope that SR2 devs would give modders access to testing hooks and prerelease versions so that the mods can be kept up-to-date with SR2 releases and keep working.
I like your concept a freezing a design, but I'd like to suggest that the penalty for changing a design should be risk.
In the current version of SR2, all the parts are 100% reliable. But in the real world, risk is the reason spaceflight is expensive. I would like future versions of SR2 to add the possibility of parts failing.
I want the SR2 campaign player to make tough choices between making small tweaks to a proven design versus taking a leap with new technologies that promise higher performance.
The player can reduce risk by operating the part in ground tests, dedicated flight tests, or as a ride-along test after the primary mission is done.
Risk goes up when the part is used in new operating conditions, or when a parameter of the part is changed.
So, if you are a clever player and freeze your launch vehicle design, then each time you fly the reliability of all of its parts goes up. The more trusted your vehicle gets, the more contract offers come up. However, if you don't continue to expand your envelope, you will get surpassed by others.
I think it's a fairly narrow fanbase that will enjoy what is almost purely a sandbox game. As the gamification increases with updates, and the fundamentals get more solid (mod API, customizable engines, docking, etc.) then I think more of the famous YouTubers, etc. will give more time and attention to SR2.

Don't feel bad. This is what Buzz Aldrin wrote his PhD thesis about.
It's a bit to much for me to describe in a comment post. I think there are probably several YouTube videos about rendezvous in KSP, such as Scott Manley.
Maybe I could do one specific to SR2, but the only difference is the interface. The astrodynamics are the same.
@AtlantikWall45 is right. Since fictional Droo is much smaller and less massive than Earth, you only need about 4500 m/s DV to get to orbit. But with RSS you need about 9000 m/s. So you need a much bigger to rocket for RSS, and they will be labeled as RSS in the gallery.
I once did a sim study with some astronauts to see if we could tow Dream Chaser on a rope behind a C-17. The purpose was to get the DC on condition for a piloted approach and landing flight test. Fun project.
Also, your post reminds me of an idea for a mod that adds somewhat realistic failures, based on actual historic mishaps. In some cases those failures just cause a degradation in performance, but in other causes the whole part explodes. Some failures trigger some kind of warning of impending doom, others happen suddenly.
I think it would be an interesting challenge for the design of the craft and the design of the automation.
Oh, one other thing I've noticed in my experience in the world... Animal metaphors for people generally don't translate well across cultures.
I really have no idea what you mean when you say you are a monkey.
@AnotherFireFox - you know I love you so I hope you don't mind some unsolicited English advice... When you say "Make a short video..." it reads like a command to me, the reader.
If the subject of the sentence is Andrew, you should include his name. Also, it may be considered rude to write this request as a command. Please consider softening the tone to be a request: "@AndrewGarrison, would you please make a short video about using the RocketEngine script to make a new engine from scratch?"
I'm guessing that before astronauts are added, there will be more options for capsules, cockpits, habitats, etc. Hopefully all of them will be scalable like most SR2 parts.
I wouldn't stress about previously built craft that are the wrong scale or custom crew modules. That's par for the course on early access, sometimes you have to rebuild when new releases break your design.
Inflatable structures for habitats, wings, buoyancy, etc. would also be a very cool addition to the game. However, I can guess that the physics modeling is nontrivial.
spaceflight companies that weren't state-owned or heavily funded, ... But now, there is finally a company that is playing real world career mode; SpaceX.
SpaceX gets a lot of revenue and guaranteed loans from the US government (NASA and DOD.) For example.
I would like the astronaut characters to have specializations that improve as they gain experience. I never liked the KSP pilot/engineer/scientist categories, stars, and special abilities.
Piloting skills can be developed in aircraft, suborbital flights, near-Droo docking, etc. High-skill pilots can stabilize unstable vehicles, optimize launch-to-orbit trajectories, learn to avoid overshooting when pointing the craft in a different direction, precisely landing on a selected place on a surface (runway, pad, or just a flat spot with no boulders), or do "automatic" docking like Mechjeb in KSP. Maybe the button to slow down time should only be available when a skilled pilot is on board.
Astrodynamics skills can be developed by planning multiple maneuver nodes, flying to different SOIs, and rendezvous with other craft. Highly skilled astrodynamicists can take user instructions like "launch to rendezvous with target", "Hohmann transfer to target", "deorbit to land here", etc. The higher their skill level, the more optimal their plans become (combining plane-changes with apoapsis changes).
Science and instrument specializations could be in categories like geology, radars, spectroscopy, biomedical, cryovulcanism, etc. Skills in these areas increase each time a scientific survey is made. Highly skilled scientists will recognize opportunities for science and highlight them. That means picking more productive landing spots, more efficient global surveys, picking better surface samples, and more breakthrough discoveries (orange soil on the moon!)
New recruits come with random skill levels, but skills can be increased in any category. Natural pilots can learn science. Scientists can learn astrodynamics. And so on...
Everyone should try building a lot of different things and find out what they like to build. Maybe landing an SSTO gives you a feeling of accomplishment that other projects don't.
By default the properties, inputs, and instructions should be for the current craft, but it would be useful to be able to script for other crafts that are not currently selected.
Craft properties:
- angle of attack
- angle of sideslip
- flight path angle
- pitch error (difference between nav sphere selection and current pitch)
- heading error (difference between nav sphere selection and current heading)
- roll error (do any modes try to maintain a roll angle?)
- linear velocities (north, east, down)
- linear accelerations (north, east, down)
- Euler angles (pitch, roll, heading)
- angular rates (P, Q, R)
- dynamic pressure
- static pressure
- Mach number
- Reynolds number
- weight
- thrust
- drag
- lift
- lateral force
- moments of inertia
- center of mass (x, y, z relative to datum)
- x, y, z relative to target
- angles to target
