This is really nice, with the caveat that that disclosure is self-reported. A lot of times, the AI disclosure is buried in the game description text after the fold.
Unfortunately, there's still no community tagging, and a lot of games use assets without saying anything or publicly making a big deal about how they don't (see: Romeo is a Dead Man). Still, better than nothing!
