As I said privately to Laurent before, I don't see the point of such a package. IMO, it adds overhead on Config which already could benefit some fitness plan.
Furthermore, flexibility is very important here. This class won't fit everyone's needs in a large sense because it cannot be adapted to everyone's way of doing applications.
It is like me trying to push my ACL solution and expecting it to be the standard way.
PS: I don't mean to hurt, I am just expressing my POV. Laurent made some other classes that I find a lot more useful.
