Maybe I misunderstand your proposal. It seems that what you are saying is
the following:

Suppose we have a secondary DNS server. It knows about DELEG but not
anything else. It gets a zone transfer and the zone has a delegation
type record that the server doesn't know about. Now the secondary cannot
serve the zone because it doesn't know the interaction with NS.
