But the WSGI Lite protocol is actually backwards compatible with WSGI. You can write code to the WSGI Lite API, and transparently interoperate with existing WSGI servers, apps, and middleware.
Correct me if I'm wrong, but doesn't this mean that it's WSGI extra rather than WSGI lite? I mean, you don't generally consider the lite version of something to have the all the features of the full version and then some.
