! Have you tried:
! listen-on-v6    { none; };

No, I have

listen-on-v6    { ::1; };

And as I understand, this is something different: this is where named
will respond to queries from clients, while my issue is with the
servers named asks when doing recursive resolve.
If anything, then "query-source-v6" would be the appropriate one, but
that doesn't seem to allow "none;".
