Ultimately I'd like to refactor the Catalyst main request building flow to be
layered using PSGI Middleware or similar (or at least that is my thinking now)
and part of that would allow us to using middleware for some of th stuff we use
plugins for (like authentication, etc). I think over the long term the PLugin
approach has not really scaled well and often we find its hard to fix things in
Catalyst core because some popular plugins would break. I think we could make
this more robust, but that is probably not anytime so, although one step might
be to try and refactor the catalyst dispatcher into psgi style middleware (make
it easier to plugin in a new one, for example)
