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.

Unfortunately, it is.  In particular, servers need to know what to
expect the browser to send if a user types non-ASCII into the url bar.
There are real interoperability problems out there due to differing
server and browser behavior in this regard.

It may not be an _html_ interoperability problem, but it's certainly a
_web_ interoperability problem.

What's displayed is not a concern, in my opinion, in terms of
interoperability.  What's put on the wire is.  The constraints that need
to be imposed are much looser than on <a href> (e.g. we don't need to
define exactly what url gets loaded if the user types "monkey" in the
url bar), but sorting out the non-ASCII issue is definitely desirable.
