No, definitely not.  You cannot depend on the registry to enforce this
if you use "external" nameservers.

Of course, but if a host object is renamed there is at least a
mechanism by which you can be informed of it: the poll queue ought to
send messages about such a thing.  (I worked with someone who also
broke this on purpose because, well, he was too lazy to do it the
right way, IMO; but the mechanism at least exists.)

It's for sure impefect.  I think an awful lot of its misfeatures are
really the effect of the RRR model and its implementation in
ICANN-land ca. 2000, but I know others disagree with me about that.
