But as you say, this would conventionally be handled just by having a separate Host per Hostname, eg Host foo.ipv4 Hostname 192.168.0.1 Host foo.ipv6 Hostname fc00::1
It would be more intuitive to use Host foo Hostname 192.168.0.1,fc00::1 # many # more # options in .ssh/config and (for example) ssh -6 foo ... if you want to select the AF at all. That would be consistent to Host foo Hostname foo.example.com # many # more # options for relying on a naming service. BTW, changing /etc/hosts, LDAP, external DNS or whatever might not be an option due to to local restrictions.
That is, I think there should be a principle of "minimise client guessing games". So, even if multiple entries makes sense for Hostname, I would still be inclined to disagree with any proposal to add this feature.
I disagree. ssh handles DNS returning several A and AAAA records quite well. Having multiple IP address entries in the Hostname line would be the same "guessing game". IPv6 should no longer be ignored or considered as "not important for us". Dual stack is state of the art today.
