I'm sure that many parts of those contemporary documents were adhered to
closely at the time, by a technical community smaller and more
integrated than today's.  It doesn't follow that all the recommendations
in those documents are rules, and that they must be followed for all
time by all other communities.

I see that text, in a section headed:


       This section suggests rules-of-thumb for using the domain system and
       configuring your database which are appropriate in most cases, but
       which may have rare exceptions.

       Zone delegation

          When a domain wishes to become independent from its parent, the
          RRs which mark the delegation in the parent and child zones should
          be carefully synchronized to minimize the possibility that
          resolvers become confused.

You still haven't convinced me that this guideline (or suggestion,
recommendation, rule-of-thumb, or consideration) is actually a
requirement, or that the requirement is binding on all operators.
