While I understand that for most developers, Proton is preferred, and is just easier...
I personally would want to (as a developer) build with Linux in-mind as the primary platform, and consider Windows to be an afterthought. Now, I get that this is a really radical approach, but it's actually something that a lot of emulator developers do with their builds, prioritizing Linux.
That being said, native Linux porting from Windows is uhhhh, difficult so Proton will always have a place.
