Thank you for this suggestion. It is a reasonable algorithm, but it does
require a lookup of existing NS records first, to determine if there's
any in-bailiwick glue.
So far, none of the responses have indicated that there might a simple
operation to unconditionally delete all in-bailiwick glue under a given
name. So I guess I will combine your idea and other ideas, and see if I
can come up with a reasonable solution.
