There's something to be said for having a standard, known SKU, both as something for developers to target if enough people own it, and for users to troubleshoot if they're e.g. having an issue running X game.

This kind of already exists with the "Deck Verified" label on Steam games.

That said, this sounds similar to Valve's upcoming Steam Machine and I'd much prefer that to be the standard console/PC hybrid to keep the Linux gaming momentum going, and perhaps one day I can ditch Windows for good.
