In my experience, the Linux ports never got any attention from the devs either way. They'll usually have worse performance, not be on the current patch and in at least one case, Binding of Isaac Rebirth, not be compatible with the DLC as the DLC works in some hacky way on the windows version. Without Proton the steam deck would not be popular enough to warrant any Linux ports either way. So Linux ports would be doomed regardless. The real travesty is steam, with the recent introduction of WoW64 in Wine, is now the only software that requires me to run 32bit binaries on my desktop. Real annoying.
