Right, today it is.  The entire issue of delegation-only was under the
hypothetical scenario that .nl changed to a delegation scheme like
.se, which is not a delegation-only zone.

Can you elaborate on what kind of glue failures and operation errors
you're concerned about?  E.g., if you don't trust the root servers to
serve A records correctly, how do you trust them to serve NS records

I agree; other zones should avoid unnecessary dependencies as well.
