One thing to keep in mind is that browsers do all sorts of non-interoperable things for input that is not a valid URL, such as guessing that it is a hostname or performing a search with a search engine. So there's a limit to how much this can be spec'd. I agree that for certain URL-like strings that a user may type or cut & paste, there is an interop issue.
