Maybe not an excuse for you, but there are still games that don't work out of the box, and the solutions for third party launchers are still fragmented and/or not feature complete, in comparison to its native Windows client. Let's take Heroic Games Launcher for example, looking at GoG: it does not yet track hours played nor achievements (they have work in progress [1]); Lutris on the other hand doesn't even have cloud Sync.

Proton is also no complete, perhaps one day it'll be, it's not quite there yet. I've stumbled on some games that don't work (Obscure 1, Resident Evil 0, Dark Messiah, etc) and games that didn't work in the past but now works, with some flaws that are hard to distinguish between Windows' and Linux's fault (Thief: Deadly Shadows).
