actually we now properly support getting all routes as a collection in CMF routing 1.1, which would allow people to also use ``app/console router:debug`` with these routes. so we should also implement this method. that being said .. obviously for people that have a lot of routes they may want to disable this. 

for example see the PHPCR implementation in RoutingBundle:
https://github.com/symfony-cmf/RoutingBundle/blob/master/Doctrine/Phpcr/RouteProvider.php#L150
