Also, Todd, as Kevin explained, we are thinking a lot about this and the reason why this feature of multiple workspaces, users, and RBAC permissions is not out yet is that multiple organizations require different setups and we want to ensure we provide functionality that will satisfy those different needs
that's why most likely you will see workspaces and the ability to add users rather soon, but fine granular permissions is a feature way may add much later to ensure it satisfies a variety of use cases
