Eh, things didn't change when Valve ported their games and client to Linux and native SDL2. The Steam Machines didn't really encourage anyone to write Linux-native titles, and the Steam Deck runs Windows games like-native. Developers are not going to want to develop, debug, playtest and support a whole other operating system unless they have to. Unless you're already dealing with an ARM native port of your game (like Factorio or No Man's Sky), porting to Apple Silicon isn't immediately attractive.
