Since the middleware is executed inside WSGI gateway, and the gateway
can be configured to always execute some middleware, the final
application will simply have at disposal a WSGI conformant write callable.

This will add useless overhead.

To make people happy, I can just have the default implementation include
the required middleware by default.

I still have to update it.
