Comment:

 The roadmap in #4556 basically says "this relay-to-relay use of ipv6 will
 happen naturally over time".

 Meaning, there isn't any discussion of whether it's a good idea to switch
 to ipv6 if both relays support it, or leave those tls connections on ipv4
 since we still mandate all relays be able to speak ipv4.

 So: is there some advantage to moving relay communications to ipv6? Maybe
 the routing is different and better? (I could imagine the routing being
 different and worse, in the case of folks who have the more centralized
 hurricane electric ipv6 connections.)
