To close this loop -- the change in -08 isn't sufficiently prominent IME; while the general nature of the change is listed in the Abstract, the actual normative text is very hard to find. Given that this is a pretty fundamental change in the operation of a URI scheme, I'd think it at least deserves its own section, if not a separate document.
