> I have not needed any of these features to use proton on the games I own so I’m still none the wiser as to who the target is for this...

...it's people who need these features and fixes? If you don't need them, then you don't need them, and you don't care about this.

With the addition of this comment, it seems like your commentary here boils down to "Why would I need this fork of this project that solves a specific set of problems that I neither have nor have bothered to understand?".

I do agree that it's reasonable to not waste time learning about problems you don't have, aren't really important if you don't have them, and that you're not interested in learning about, so don't make the mistake of believing that I'm throwing scorn your way.
