 figuring this part out.

 We had some discussion [http://meetbot.debian.net/tor-meeting/2019/tor-
 meeting.2019-12-05-18.00.log.html in a recent meeting] about the original
 intent of this ticket.

 I think to address the need of "default STUN servers are blocked for the
 client", it would be more interesting to pursue ways in which NAT punching
 information for the client could be sent over the domain-fronted
 connection to the broker. Some discussion on #30579 laid out reasons why a
 more private way of getting ICE candidates is desirable.
