It would also be nice if the relay, itself, performed self-checks of this connectivity and printed a warning log if some failure-threshold is reached (and possibly disabling the IPv6 ORPort). But, in reality, this is a hack
I wouldn't call it a 'hack', I'd consider it a reliability feature.
Relays already check that their IPv4 ORPorts are working.
Doing reachability checks for relay IPv6 ORPorts is a bit more complicated, because we have to teach relays to extend over IPv6 first.
Here's the master ticket: https://trac.torproject.org/projects/tor/ticket/24403
And if relays use authority IPv6 ORPorts to upload descriptors, they will get connectivity checks for free: https://trac.torproject.org/projects/tor/ticket/24777
