Other information

There was a TAG review in w3ctag/design-reviews#358 with some interesting discussion. One of the points I was concerned about there was that it:

1. should be possible to put this behind a separate permission, if the UA wants to do so, and

2. should be possible to combine the permission request for video with the permission request for pan/tilt if the UA wants

so the API ought to be structured such that both of those were possible.

I think this is a good idea, though it's possible I'm being optimistic in thinking we can implement this without any major changes to the API. Since AFAIK we don't have PTZ controls on our short-term roadmap, clearing up any API impact might be our primary interest at this point.
