Yes that was my thinking also, because supporting modular rendering

I guess that's me!
I assume protocols.http's refactored state will remain in the core
twisted? It would seem silly not to, and it also seems silly to do
major refactorying without having someone prepared to port twisted-web
to the new api. So I'm volunteering, but I might need a lot of help
along the way.

Of course not, I didn't intend to imply that it was, a code fork in the
technical sense is necessary, I did not want to fork the project in a
