We'll see if Valve's partnership with Arch expands, it's been suggested that Valve could do signature verification on the OS as a fork of verification.

It would be nice of Valve could put this issue to rest considering its the top blocker on some leaderboards games.

Personally I hope they solve it by making it "opt-in" for "Verified Multiplayer" as opposed to opt-out 'take it or leave it' as many games get canned robbing purchasers of their ability to enjoy abandoned games.
