It could be used for some games, particularly simple ones without much need for precision, but I don't see how you could generalize that to all VR games which exist. Take the common case of aiming a gun, if you mime the action of a trigger pull with just hand tracking there's zero tactile feedback as to where the actuation point is, and if your gun hand twists the wrong way or your other hand occludes it then it's just going to fail because the headset literally can't see what you're doing. It's not magic.
