This problem only becomes evident if there is a need for wildcard
records. It may even be a design goal to make wildcard records
impossible to make it harder for manually managed zones to set the
NRR for the whole zone.
That would be a problem. I give all of my users subdomains that map
to subaddresses, e.g. farp(_at_)joe(_dot_)iecc(_dot_)com ->
joe-farp(_at_)iecc(_dot_)com(_dot_) I
really don't want to have to export my entire user database into
the DNS.
