More precisely, the idea is to convince authors of existing frameworks that 
provide those services, to enable their frameworks to be run under various 
web servers, and the authors of web servers, to support WSGI so those 
frameworks can run.

To a limited extent, WSGI itself can support new "ultralight" frameworks, 
in the sense that WSGI is intended to allow easy creation of "middleware" 
components.  For example, one could create a WSGI "session manager" that 
looks at a request and adds a session object to the 'environ' dictionary 
under a special key.

The point is that since it's a standardized API, you can plug together 
whatever components you want or need.

That's not in scope for the WSGI, whose goals specifically state that the 
specification must *not* require anything added to the standard library.

This does not preclude separate proposals for standard library enhancements 
based on WSGI; it's just that they're not a part of *this* proposal.
