I don't get the purpose. WSGI was meant to low level to cover the common minimum. If you want request, response semantics, use a higher level library - I use werkzeug which wraps wsgi, or flask which is small web framework built on werkzeug.

I don't think anyone other than wsgi library implementors code to WSGI. WSGI would be a problem if that's how python web programming was to be done - but that's not the case.
