I dunno. There’s already a separate Linux VR DB, as Proton doesn’t really do that for games that support flat-screen and VR. https://db.vronlinux.org/. Unfortunately it isn’t kept that up to date, I requested American Truck Sim be added over a year ago now, and it still hasn’t been.

Anyway, as we see more and more enshittification (not that I would expect ProtonDB to enshittify any time soon) I’d rather my services and websites to be more spread out as compared to all on one website. I can type in one URL to check on flat-screen games and a different one to check on Steam Frame compatibility, it’s no big deal.
