GUID is not "a place to store a canonical URL" or any such thing.
Changing the slug will invalidate the URL stored in the GUID, but the
GUID must remain unchanged. Storing the URL there is a quick-n-dirty
way to provide a string that will probably be Globally Unique.

If anyone would like to propose another way to generate a reasonable
GUID that is less confusing to db peekers, now's the time.
