Description

In #4115 it was noted that bridges were using naked dirport connections. That was clearly a bug, and has been fixed.

But it is less clear what public relays should do.

In favor: encrypting dir fetches improves their resistance to tampering on the wire, including tampering of unauthenticated stuff like the X-Your-Address-Is and Date http headers.

Against: it increases the load they place on the authorities, both in terms of CPU (all those bonus TLS handshakes) and sockets (since TLS connections are held open for a while).

It's possible the 'against' item isn't so bad, since authorities often have tls connections open to relays already. Somebody should investigate how much that's really true.

Finally admitting that 0.3.??? was a euphemism for Tor: unspecified all along.

I'm going to close this ticket in favor of #11973, which has essentially been following a parallel thought process.
