It might not be friendly for new Linux users but I feel in control using it and keep it maintained and clean easily.
I usually recommend Vanilla OS for non-tech savvy people, in case you're looking for something that just works. It will probably become limiting for you after a while since you like tinkering.
If Valve managed to acquire a good marker share, developers will care about having something that works in Valve's SteamOS, Microsoft will push developers to native ports if they tried to degrade Proton ports, so I think they'll prefer to keep their control over DirecX.
