Even outside DNSSEC, where it absolutely would be a problem, there are
some context for specialty applications where the difference between
the two types of negative answers is meaningful. The examples I can
think of off the top of my head are proprietary, but the general idea
should hold: if two things have semantically different meanings,
people somewhere are making use of the distinction.
