Reusing authentication/permission across routes

[dorshinar]

Hi!
I was looking at docs about creating RBAC based routes, and I see that permission scopes are defined in multiple places rather than shared.

Example scenario - <Admin /> page that requires write:admin scope. The check happens in the beforeLoad of the route.
I have another route, not a child of <Admin />, open to all users that shown a list of links. For admins I want to show the link to the admin panel based on whether they have the write:admin scope.

I don't want to inline the scope in both checks as that may cause a drift in the future. What is the best way to share this scope information?
