ACL Groups and Access Levels for Memberships

It would be great to utilize the Joomla ACL for groups and access levels for each membership created. I used Akeeba's Subscriptions component which does this and it actually had more flexibility and much easier for restrictions. Unfortunately they were overloaded and could not continue development with the component. But RSMembership is still good, but the ACL would be phenomenal if RSMembership used it.
