I agree, that is an important question and needs to be addressed, but
UUID doesn't address it, nor was it intended to.

Sure, but without the identifier, you would still have the question
"where did this fellow come from?"  to which the response is "Who are
you talking about?"

The identifier at least allows you to refer to him by name..

Is your argument that we SHOULD have good metadata (I agree), or that
we SHOULD NOT assign UUIDs?
