I think separating it out into a separate document that can proceed at its own pace is a good idea, but there are important specific use cases to standardize.

I think there are requirements on comparison/equivalence/canonicalization that need to be normative, and what we have, now, is normative but misleading or incorrect. A URL needs to be equivalent to the URI it parses into.
