That's what I thought we were talking about. This has the benefit that you
don't need to gather STUN/TURN for the other addresses that you know you
are going to discard.

Regarding intermediaries, I expect that even for less-well-provisioned
WebRTC app providers, there typically won't be any intermediaries, at least
none who have access to the signaling traffic.
