Hmm...  Yes, well I can see this as useful (though not much more than a few
lines of any programming language?) if you intend to maintain generic
placeholders...but not if you want RFC-compliant matching A/PTR.  Granted,
you should not drop mail in such cases, but many do.  I guess tools and best
practices take time to catch up to technological leaps.  ;-)

Or do you actually create A's matching your generic PTR and heavily rely on
CNAMEs?  Of course that simply won't do for some standard RR types.

As much as I dislike djb in general, the way tinydns auto-creates matching
PTR (and also provides a mechanism to disable as needed) for each A RR kinda
makes sense.  Granted, it doesn't do IPv6 at all without 3rd-party
hacks...but they do at least exist.
