> @eehakkin Was the reason for the new `true` semantics to be able to acquire the camera without altering the current pan, tilt and zoom values?

Yes, exactly that. So with the new `true` semantics it is possible to acquire a pan-tilt-zoom camera (instead of a static camera) during getUserMedia without altering the current pan, tilt and zoom values and then later pan, tilt or zoom the acquired camera using applyConstraints without a new prompt (as there is no need to elevate the permission from a normal camera permission to a pan-tilt-zoom camera permission as the latter one was requested from the beginning).
