That's entirely a given -- the leasing API is under the control of the
application which can lease any set of resources it likes.

The only question here is how to avoid flashing the desktop contents
onto the HMD when you plug it in, and that means not listing some
displays as 'connected' in the default RandR requests. There will be a
separate request which lists them all.
