I think what we need is a situation where applications written entirely
with twisted.web.*, and no Nevow whatsoever, still function properly.
Breaking backwards-compatibility for all those users would be a big

I believe this is what Chris has been talking about -- right?

If we can't maintain that backwards-compatibility through wrapper APIs,
then we should leave the old twisted.web in the Twisted package for at
least one or two release cycles, pepper it with DeprecationWarnings, and
do our best to tell users to either spend the minimal effort porting
their app to tmlabs.web, or to keep using old versions of Twisted.
