When one defines a controller as a service, it would be nice to be able to wire it with routing in a snap of a tag.
eg

services:
    Controller\SomeController:
        tags:
            - name: routing.annotated_controller
              prefix: /foo #optional, maybe the other route params as other tag attributes if worth it?

Using this tag, the routes would be specified as annotations on the related class+methods (which means moving AnnotatedRouteControllerLoader to FrameworkBundle.

This would allow bundles to take control of the wiring of their routing configuration. This means that just by enabling a bundle, its routing config would be done. Of course, each bundle could provide config to change the prefix, disable/enable routes conditionally, etc.

I also think that this would mean one less file to look at for new comers (I mean routing.yml.)

If someone would like to give it a try, please do :)
