Well, Philip J. Eby explicitly said that WSGI 2.0 exists only for 
removing the use of start_response...

So I assume that it is already set in stone.

I have tried to figure out how to implement an asynchronous application 
with WSGI 2.0, but the results are not good:


def application(environ, start_response):
    def app_iter()
      c = Connection(...)
      r = c.request(...)
      for block in r:
        yield block

      data = r.get_response()

      environ['start_response'](
        '200 OK', [('Content-Type', ('text/plain')])

      yield data

    return '', [], app_iter
