> Proton is neat for sure, but unfortunately modern anti-cheat solutions expect Windows and will not allow Linux clients to connect.
Keep in mind that many people are interested in single player or local multiplayer that do not require anti-cheat solutions. They will hardly ever run into problems on that front.
I suspect the largest problem with Proton is that support will be biased towards recent popular titles based upon common game engines. Replicating all of Windows is not practical, Valve themselves will be most keen on supporting games they can generate revenue from, and community contributions will come from people who have an interest in getting particular titles working as well as the technical skills to contribute.
