[keycloak-user] Role Attributes

Hi all, I know this may be a long shot, but is there any plan to support attributes for roles? Use case: I am replacing a pre-existing home-grown auth system with Keycloak. There is metadata associated with the existing roles that is required by the services consuming the JWS. I have a very hacky plan to support what I need via role descriptions, but having role attributes would allow me to implement this need is a cleaner fashion. Thoughts? Thanks!
