Mostly in agreement. I prefer to focus on the model (RBAC) rather than a specific impl like Fortress. That is to say support the model and allow the impl to remain pluggable. That way you enable many vendors to participate in your ecosystem and more important, one isn’t tied to a specific backend (ldapv3, sql, …)
