Comment (by Sebastian):

 Extend the notion of canonical to have a canonical v4 and a canonical v6
 connection. Only in the event of a reachability check with a "must v4" or
 "must v6" flag create a new connection of the other connection type. Treat
 this second connection as canonical for the purpose of deciding whether to
 close it etc, but not for actual traffic. Does that alleviate the DoS risk
 you're worried about? If not, why not?
