There's an argument that 303 says "here's something related" instead
of the desired "here's information about a non-information-resource".
A shortcut for 303 doesn't improve that situation, but it does make
the 303 dance much more efficient, which is important regardless of
how you think about 303s. I'd be content with this outcome. If we
eventually discover some debilitating ambiguity in competing uses of
303, we'll have to deal with that regardless of how 2xx is defined.
