Native Linux games break too, especially older ones. I have had to switch to Proton for several games I used to run native because their native version has stopped working after some library change.

At this point I have more faith that a game with solid Proton/Wine support will work on the long term than a native one.

There are many exceptions in both directions of course, this is just my personal experience with the games I happen to be playing.

It wouldn't be the worst thing in the world if Proton/Wine became the standard supported runtime for games.
