Fair enough.  There's certainly no need for two NS records if nobody's
following delegation here.  In the case of dynamic updates, one NS
record might actually be better: there's no worrying about update
forwarding between slave and master.

Will a zone even load with zero NS records?  It's not something I've
ever tried, though probably should for grins.
