Apparently, Valve keeps getting builds that were never run through Steam at all, which is how games end up with broken launch options or missing depots.

Four months or so Blizzard dropped a new season for Diablo 4 (along with a new game update), while being "Steam Deck Verified" and the new version of the game didn't launch at all on Linux anymore.

The Proton team had to make an experimental Proton build which took around a day before it was fixed iirc.

So really, even AAA devs can't seem to test launching their games for all scenarios.

    A game can be "Steam Deck Verified" by Valve without the publisher making a request. In fact request by the publisher is the last option after automatic heuristics and Valve identifying a game as improtant.
