Well, the draft only proposes that it identify the language.  Putting
a page there so the server returns 200 was a step I'm pretty sure the
editor made independently, w/o considering the ontological
implications of doing so or what our httpRange-14 finding has to say
about them.

No probably not.  But we've accepted puns similar to this in the past,
particular wrt namespaces themselves. . .

Let's not be hasty -- do we have any extant examples of languages
which _do_ publish separate URIs for the language and the spec.?  Do
any of these use the 302 response for the language URI?  What, for
example, is the URI which identifies HTML?  N3? Python?
