 Does this matter?)

 > IMO yes.  If we need another complexifying argument or flag in
 purpose_needs_anonymity() to tell the "fetch from source" case from "fetch
 from bridge authority, that's better than running into trouble down the
 road if fetch_bridge_descriptors() does something foolish.

 I agree, the challenge will be to pass this flag down to where it's used
 (or derive it from the dir_connection_t / function arguments). Actually,
 it should be pretty easy - just check if the bridge is a configured
 bridge, and if it is, allow us to fetch bridge server descriptors from it.
