That's completely fair of course, but with how much of a bitch decompiling Renpy 8 is currently, expecting anyone else to dig into the script beyond Sancho's work on their mod is probably unlikely.
You are of course right. I'm willing to help anyone who tries to create a walkthrough, but to be clear, even if you were able to properly decompile it (or you got the sources from me), you'd still have a very hard time, because
all choices in this game just store an identifier that records that you took that choice, so it is much harder than in other games where many choices only affect a few lines of script and you know they can never do anything else because they don't change any variables.
And RtS also has nothing like traditional relationship points, etc., that are just added at the point where you make the decision, but they are calculated only when they are needed, based on potentially every choice you ever made.
So writing a walkthrough would not be easy in any case. Which would apply even to myself, since I can't for sure know yet whether I might in the future use some decision you took earlier to influence something. I don't do things at random though and I know for many choices where they will eventually lead to, but details, not so much.
My best advice is to pick the choices that you like, maybe have a look at what stats they change (you can enable the notifications and then check, but most of the time it will be pretty obvious). If you do miss a scene in the end, ask here or just try a few different choices. As I said, I don't do things at random, so usually it will be clear, at least once you know what the scene is that you are missing.
