They cause operational problems to some people. Different caches
a sensitive to different problems.
RFC are written so that *everyone* and *everything* involved in
the protocol can know what to expect.
In this case for every zone parked on the servers everyone expects
to see a NS RRset which matches the parent delegation and a SOA
record which has valid details in it.
As long as you meet the protocols expectations it doesn't matter
how you implement it.
Named really is not optimised for a roll like this. Named
has a much more complete implementation of the protocol than
what is needed to park a zone.

The right way to do it with named is to create the zone
with the same NS RRset as is in the delegation. The zone
has just the SOA and NS RRset.
If you have multiple zones with the same NS RRset they can use
a common zone file.
