To elaborate a bit: PowerDNS Authoritative Server certainly supports
resolvers that do strict query minimization, but only if the data in
the zone it right.  Rectifying includes adding records for empty
non-terminals in the appropriate places, so that a proper empty
NOERROR (aka NODATA) is returned if there are child records. 

After editing a zone, a rectify is needd. When using the API that is
taken care of by default (on a reasoably modern version). But not if
you edit the DB by hand.
