It is a relatively common practice to add custom metadata to the route definition in Angular 1 and then drive some behavior of the application from this metadata.

Good example is permission management where a particular route should be accessible only to admins.

The proposal is to implement this as a data property in the @RouteConfig annotation:

@RouteConfig([{
  path: '/settings',  component: SettingComponent, data: { adminOnly: true }}
}])

This data should then be available to components as an injectable or property of the current route.
