Developers are unable to opt out of the system and Valve will just put a "verified" tag on a game with zero input from a developer.
Valve needs to set proper expectations of who to be mad at when a game breaks on the Steam Deck if the developer themselves never pledged support.
Most users don't understand what an OS really is or how a game works on the Steam Deck (SteamOS) instead of Windows.
This is a big claim, is there evidence for this? I'm an end-user, not a developer, but there are plenty of games in Unknown status. I would assume that should be the default, not Verified.
I can see an argument that Valve has incentive to have flagship games get that Verified badge, but there is also precedence for them downgrading popular games after launch. For example, Spider-Man 2 recently went from Verified to Playable (rightfully so, in my opinion).
Some popular examples of this;
1. Baldur's Gate 3: It has Verified status, but the community unanimously agrees that the performance is very poor around Act 3, and makes the game nearly impossible to finish on Deck.
2. Spider-Man 2: It had Verified status at launch, but performed poorly in terms of graphics and visuals. It was recently downgraded to Playable status, meaning you have to change the graphics settings to comfortably play the game.
Personally, I think Valve's definition of Verified [1] is too vague. The 4 criteria don't actually mention anything about graphics or performance - it only says it should have "good default settings". What does that actually look like when you play it? Additionally, how much of the game is tested when evaluating those settings?
Valve doesn't actually advertise the process of how the badge is assigned, that I'm aware. Is the game 100% completed in evaluation? What percentage of input is there between Valve and the developer? Are certain publishers or developers given any bias or leeway? That part is still opaque to the end-user.
I think the Verification process is a good first cut at standardizing PC specs, where before there weren't any. But it can definitely be improved.
