I too used mine as a backup. I don't have a working one atm, but technically my steamdeck works for most of the games I'd want to keep up with, if a bit harder to use. I can even do ffxiv, though definitely less skilled using the steamdeck. I might try with a dock and my 8bitdo controller and see how that feels (already have both, but haven't really tested it since I use that controller for switch instead).
