That is truly terrible user experience. Pure example of form over substance.

Interesting, this is very project specific so might be tough to implement for general user-base.

I personally dislike Pundit's way of defining permissions, but as always it's a preference.

You are allowed to mix any roles in any combinations. This shows only a flat hierarchy, but I'd love to explore that in an example sooner than later :)
