Is there any place in the Web platform where "canonicalize" is exposed by itself in a Web-facing way? I think resolve against a base and parse into components are the only algorithms whose effects can be observed directly. I think we only need to spec "canonicalize" if it turns out to be a useful subroutine.

There's also the related question of what browsers should do with input typed into the URL field. Other than establishing that these rules may be different between the URL field and URLs present in content, I'm not sure this is amenable to spec. But perhaps a survey of what browsers do would be useful.
