Not even for games.
Proton has been a Godsend to weirdos, like myself, that game on Linux, which is why, when everything else is equal, I will give my money to Valve rather than anyone else who runs a storefront. It's still not as out of the box plug and play friendly as Windows for brand new games... Although given the state that games release in these days that make me question what exactly is the difference between early access and a full release, I don't know that anyone gets a smooth plug and play experience on PC, or even consoles for that matter, at launch.
