But we do use the recommended version list to select fallback
directory mirrors. So when we next rebuild the fallback list
(later in 2020), all relays on 0.2.9 and 0.4.0 will be removed.

Clients may use relay protocol versions to choose paths, when we
add new features that they want to use. But that's a long way away.

All supported Tor versions (and 0.4.0) support the most recent tor
Relay protocols. So clients don't have any reason to choose between
relays based on versions right now.

In Tor 0.4.4, we'll introduce a new Relay protocol for IPv6 extends,
to support relay IPv6 reachability checks. Clients will ignore it,
until they start doing IPv6 extends. (We think we need more IPv6
relays, before clients can safely use IPv6 extends. In the meantime,
clients just do IPv4 extends, and every relay has IPv4.)
