You wouldn't be able to (and can't) do this on competitive PC/Steambox games though because you can just fake it on PC, so gamepad players would never be able to compete.

It also works reasonably well for cooperative games. I beat Portal 2 with a friend this way.
In any other context that would be the foulest cheating... but in the context of game-design for vastly different interfaces, it's a perfectly reasonable handicap.
