Hi,


Currently the bridge authority 
(https://metrics.torproject.org/rs.html#details/BA44A889E64B93FAA2B114E02C2A279A8555C533) 
doesn't issue a family ID for bridges. For relays, it's the directory 
authorities that verify the family cert and issue the family ID.

Support for family IDs on bridges isn't something we'll get to in the 
near term, but it's definitely something we have on our radar.

Cheers,
