I've been playing games on Debian Stable for many years now, and although there were some issues back when the Linux Steam client first came out, in past five or so years, I noticed that I tend to forget to even check whether a game works with Proton before buying, and I haven't had any issues playing all sorts of games.
Of course, I don't play AAA slop that's essentially rootkits with a game attached on the side, but even more reasonable AAA titles tend to work just fine.
What I'm trying to say is that this "debian stable is from previous century" confusion needs to die. They had one or two slightly longer periods between two stable releases, many years in the past, but that seems to be all people remember.
