Which was/is the context raised by the original poster.

True, but unless someone knows in advance what zones that server has,
there is no way of finding such an "unlinked" zone. It can't be found
by traversing a chain of NS records from the root. So that zone will
be like bigfoot or the Loch Ness Monster: it might "exist" but
nobody's been able to find it. Debating the existence of these
unlinked zones is a bit like asking if a tree makes a sound when
it falls down if nobody is there to hear it.
