Given it is possible, why not implement it on the rift s as an experimental beta feature? 5 years ago something like this would be unheard of and seen as insane so if we give hand tracking a year or two on the rift s I can't even imagine what it would evolve into. By not implementing it on the rift s it is instead slowing down development. Besides, I can certainly imagine a mod that will allow you to use the force with your hand tracked hand and simultaneously use a controller to control the saber for the game vader immortal.
