Ah yes, the composite thing IIRC - I didn't know this was a middleware.

Should those be middlewares ? ISTM that they should in the front of
the stack instead, and that a stack of middleware should be dedicated
to a single application -- for the griefs you mentioned and probably
other problems.

I mean, one call does not visit several application, and this is some
kind of dynamic rewriting of the stack..

Another possibility would be to define a
"get_application(environ=None)" method so the middleware is able to
return the right app at the right moment
