I now realize that things may be a bit more complicated than that, as
connections to e.g. 'invalid at twattle.net' result in a faultless ipv6
connection that continues all the way through to the password prompt.

Perhaps the issue is limited to cases where the name resolution happens
via /etc/hosts, and returns results for both protocols? (It is *not*
limited to connections to "localhost", it also happens when /etc/hosts
specifies both an ipv4 and an ipv6 address for a remote host.)

And KiBi, is your use case covered by these considerations?
