I would like to see an alias feature in the Routing component.

Usage

If you have a project and you use the SonataAdminBundle, the dashboard is at /admin/dashboard. I don't like that and want to use /admin. If we have an alias feature, we can do something like this:

admin_dashboard:
    path: /admin
    alias: sonata_admin_dashboard

We can even bring it a step further and say that an alias will copy all route data in the new one and you can override very thing. That means we can do something like this:

route_1:
    path: /post/{year}/{slug}
    defaults: { _controller: ... }
    requirements:
        year: \d{4}
        slug: \w+

route_2:
    requirements:
        year: \d{2, 4}
        slug: [0-9a-zA-Z]+

What do you guys think of this new feature? If the reaction is positive, I will start looking at how to implement this in the Routing component.
