I'd prefer that WSGI 2 was defined in terms of a "bytes with benefits"
type (Python 2's ``str`` with an optional encoding attribute as a hint
for cast to unicode str) instead of Python 3-style bytes.

But if I had to make the Hobson's choice between Python 3 style bytes
and Python 3 style str, I'd choose bytes.  If I then needed to write
middleware or applications, I'd use WebOb or an equivalent library to
enable a policy which converted those bytes to strings on my behalf.
Making it easy to write "raw" middleware or applications without using
such a library doesn't seem as compelling a goal as being able to easily
write one which allowed me direct control at the raw level.
