just for my curiosity, where do you draw the line for technical
compliance?  do the servers need to serve the zone?  does the served
zone need to have the same NS RRset as the request and hence parent?
do the servers need to be able to answer compliant dns queries?  over
tcp too?

your first paragraph quoted above would seem to say that none of this is
needed.  the registrar's job is to stick the delegation in the parent
zone and actually functioning name service be damned.
