Well I definitely don't think we should constrain a spec editor to being 
forced to use text he didn't even write, that seems like a very poor way 
to write a spec. Especially given that here the text is already spread 
across two specs (URI and IRI).

I think it makes sense to be conservative and say that URL synatx 
conformance requirements should probably not change from what the IRI spec 
says today unless there's a really compelling reason, though.

Well unless there's a very good reason (e.g. following the current specs 
involves a security vulnerability or something like that) then I'd think 
that was a reasonably strong technical requirement, sure. But that's 
independent of how the spec is written. It's trivial to write a spec that 
uses existing text while making all existing implementations 
non-conforming, for example (just add a line that says "implementations 
MUST NOT do what the following section says" or something...).
