Hmm maybe. It's even possible this might have been why the Vive was halted on release and reworked.
As I remember, they initially were going to release without the camera, but had a last minute change of plan, putting a decent delay on the release date but it then came with a camera.
Me I've not found much of a need for the camera, and so never really understood why they thought it was worth halting production and redoing the Vive for it.
But handtracking... yes maybe.
