 Sure. No bridge operator emails then.

 the majority of bridge traffic). But I would not treat differently bridges
 from relays. Not only those relays are EOL but some have bad TROVE issues
 so imo we shouldn't behave differently.

 Ok, so I think there are a few tasks remaining for this ticket:
 1. Work out how many bridges are on old versions rejected by this patch
 2. Decide if we want this change to apply to the bridge authority at the
 same time as the directory authorities

 And separately:
 3. Check that the default bridges are on 0.3.5 or later

 Marking as needs info, because we need to know how many bridges are on old
 versions, before we merge this patch.
