I'm not a routes user, so my answer might be somehow wrong, it is
mostly based on the knowledge that I have of the TurboGears routing
system.

The routes integration was not used by TurboGears itself, was there
due to Pylons and was hijacked to always route to the RootController
which was then in charge of the real routing. This is the reason why
you can only route to Pylons controller using routes and not to
TurboGears one, losing so the TurboGears features like validation,
expose and so on. If you add routes that route to a TurboGears
controller the controller itself will try to route them again,
obviously doing the wrong thing

Somehow you might be able to use routes with validation and expose by
creating a Pylons controller that inherits from
tg.controllers.decoratedcontroller.DecoratedController but keep in
mind that this might break any time in the future.

The TurboGears way to manage regular expression based routing is to
handle them inside the _lookup method and return the actual controller
instance that has to handle them with the remaining part of the url
for which the dispatch has to continue from the returned controller.
