That is just irrelevant and of no importance, since the only hosts
that use DNS64 and NAT64 in normal life are IPv6-only hosts.

There is a side issue of what happens if a synthetic IPv6 address
is referred to a non-IPv6-only host, but that is a whole other
problem that cannot be solved at the RFC3484bis level.
