I guess it would be reducing the need of terminal usage as much as possible. That’s still the only thing a common user struggles with, in my opinion. The rest is just difference or has nothing to do with Linux.

With Linux gaming is rising currently, most common problem is kernel anti-cheat games and it’s not Linux problem, for example. What are devs supposed to do? To develop literal Windows kernel compatibility layer or something? But Linux may do stuff on their end to make cheating difficult to keep game studio’s happy but that would also mean to stray away from its philosophy. As a general platform, it would be hard to do this anyway. This would be possible per distro basis. Maybe Linux dev circles are already discussing this, maybe not, I don’t know honestly.
