yes, this. i don't know if it was the same game another another where the devs said that while linux users send the most bug reports they are also the most grateful about having a game that runs on linux, and all their reports genuinely helped make the game better for everyone. (wildly paraphrased from faint memory)
in other words, if you want your game tested and get good feedback for it, do release on linux. maybe even release on linux first. linux users will love you for it, and you get to release a more polished game for a wider audience on windows.
Personally, I think it's probably best to test with Proton as part of a game development cycle to reduce the overall complexity in terms of development (not that games aren't already exceedingly complex). That's just my take... especially if you want to take advantage of that extra 5% or so potential extra market share.
