Comment(by arma):

 Here are three pieces to get us started, for new behaviors if our
 preference is using bridges for reachability:

 1) #3292: if I configure my bridge line without a fingerprint, and then I
 connect and learn a fingerprint, I should not boycott the bridge if on a
 future connection it has a different fingerprint.

 2) If I know a fingerprint for my bridge, I should ask the bridge
 authority for a descriptor if it becomes unreachable, in case it's moved,
 and then remember that address across restarts. See Sebastian's upcoming
 "Automatically retrieve and store information about bridges" proposal. Or
 maybe this behavior should be 'on' for both types of user, since a bridge
 that publishes to the bridge authority *wants* you to be able to follow
 it?

 2b) I should remember a pile of past addresses for my bridges, so I can
 try them all if I run out of working bridges.

 3) If I learn both an ipv4 address and an ipv6 address for my bridge, I
 should be willing to use either.
