Would it be too much to try to get the RIRs to agree that "" get a
DNAME and all other zones get unlinked in a shorter timeframe?  i.e. why go
through the motions of many different subzones of having DNAMEs
when just one record will do for the world?

In any other Internet context, I can see this as being too many cooks in the
kitchen, but the entities serving up zones are of a reasonably
small number.
