Comment (by teor):

 Tor subprotocol version `Relay=3`, which we haven't implemented yet:
 https://gitweb.torproject.org/torspec.git/tree/proposals/311-relay-
 ipv6-reachability.txt#n635

 Subprotocol versions look like this in the consensus:
 `pr ... Link=1-5 LinkAuth=1,3 ... Padding=2`

 `pr` lines are listed in the full (ns) consensus:
 https://gitweb.torproject.org/torspec.git/tree/dir-spec.txt#n1604

 Based on `proto` lines in descriptors:
 https://gitweb.torproject.org/torspec.git/tree/dir-spec.txt#n802

 And parsed to `RouterStatusEntryV3.protocols` by Stem:
 https://stem.torproject.org/api/descriptor/router_status_entry.html#stem.descriptor.router_status_entry.RouterStatusEntryV3
