Meh, I'd much rather have Web3/WSGI 2 (and I prefer the WSGI name,
too) for Python 3 than the small update you're proposing. IMO there
are some good improvements in Chris & Armin's spec over the original
WSGI, and I would be sad to have to go back to an incremental update
that does just enough to make PEP 333 work on Python 3. (Also I think
there might actually be value in having some incompatibility to make
the distinction clearer.)
