 Replying to [comment:10 nickm]:
 > Calling this merge-ready, but for 0.3.0. I predict that there will be at
 least one impressively weird implication of removing the server_mode()
 check in we_use_microdescriptors_for_circuits().

 I predict one weird but very minor impact:
 * some DirPort reachability checks will fail, because relays will
 occasionally choose a relay that exits to their DirPort for most of the
 world, but not their address
   * in the rare cases where this does happen, there might be a short delay
 to relay initial bootstrap while the relay retries another exit
   * this has less impact on bridges, as they don't need a DirPort
   * relays only do reachability checks once, just after they start, so
 this has no ongoing impact for running relays
