The resolver would have to construct the query non-recursively. I agree
that this is a problem.

Given that zones are administrative constructs for use by operators,
and are not intended to be visible to client DNS activities -- and
well might not be visible, no matter the intent -- then how does the
upward tree-walk know when to stop?
