Does this process really work? Are standards written and then products are built to those standards, or are products built and then the standards are created from those working products?

I've been considering a web app in Python 3, but with ZeroMQ bindings and Mongrel2, WSGI isn't even on my radar any more.

WSGI isn't a web server, nor is it transport technology, it is a gateway interface. Even with Mongrel2 and ZeroMQ you can and would probably still use WSGI.
