sorry, yes, i didn't realize you were talking about updates to games. yes, valve can only fix it with a patch to proton, but they can also encourage developers to test their games with proton.

holding games back because of proton bug is not acceptable (yet), although from the players side it would of course be nice to choose an older version if the new version fails to run.

there is a very real psychological phenomenon where when software breaks on Windows, it is the software's fault, and when software breaks on Linux, it is Linux's fault

of course, that is unfortunately going to remain a problem for some time to come.
