I have yet to see a single argument that, when carefully examined,
weighs in favor of having a flat name space. If DNS query protocols
are used to locate services for any part of the name space, there is
no reason not to use DNS query protocols for the entire URN name
space.

Why complicate things in this way, when the simpler solution is fully
general?
