I'd say keep it, then.

Yes.

I agree with removing ones that are marked incorrectly.  I think it's
harmful to remove ones that are marked correctly, though.  And I don't
see any way to automatically distinguish between the two.

Anyway, that's my opinion.  I think it's useful information.  And the
fact that it is sometimes incorrect is, in my opinion, a reason to
keep it.  I support removing tiger:uuid precisely because there is no
definition of what the correct value should be.
