You are right, this hasn't been done.  A concrete proposal is probably needed.

In my view it is not necessary to have any specific exposure for these
usage restriction, MediaStreams could use private attributes to track
this.  Though I would hope that some visibility is provided, lest
there be inexplicable errors for users.  Perhaps "readonly DOMString
peerRestriction" (which would be unset by default, though
'' for b, '' in c) would help.
