Although I'm empathetic to your attempts to clean up the API, I'd offer the
advice that this probably is too well-established to advocate removal.  You
could offer it additionally, but every bit of getUserMedia code,
everywhere, will break with that change otherwise.

It *is* easy to add the new location; the problem is that you need to make
that change in every bit of code that's already out there.  I think it
would be fine to map it additionally in to navigator.mediaDevices, but I
don't think you're going to find browser vendors very excited to break
current code in this way.  From my experience with Web Audio, there would
be a lot of complaints.
