I started to look at wine/Proton as just another linux runtime. At least now game devs have sth (mostly) stable and backwards compatible that they can target. It is really important since in Linux world, things are much more prone to experience breaking changes. Also the fact that game devs just need to develop one version for both Linux and Windows makes it super easy to target proton - you even don’t need to have a separate build process. Hence we get a more ‘refined’ version than just half-assed port made by a small team or third-party.
So I’m quite happy with how things are now. It just shows how flexible and capable Linux really is. And who knows maybe in the distant utopian future, Linux (or sth based on it similar to chomebooks, but maybe not as gimped) will pick up market and we will have much more “native” runtime.
