While I agree that there is no way to say that anything aiming to be
persistent will succeed, I do think it is useful to capture the answer
to the question:  will this identifier ever by reassigned in the
normal course of business?  There are lots of reasons why you can be
wrong in the answer you give, but the answer is useful.

This is also, oddly enough, why I think UUID URNs are just fine, even
though they do not have an organizational guarantee--the cryptographic
guarantee they provide is at least as good as the typical
human-managed system.  So I can look at one in a system and understand
that it is meant to be unique.

Just my personal view, of course,
