Is mixer not needed for RBAC in Istio 1.3?

Quoted from Istio 1.3 release notes: “We implemented most of the common security policies, such as RBAC, directly into Envoy”. Does this meant for service role and service role binding and etc, mixer is not involved anymore?

Istio RBAC policies (ClusterRbacConfig, ServiceRole, and ServiceRoleBinding) are enforced in Envoy now. @YangminZhu may know more.

Yes, Mixer is not needed for RBAC and AuthorizationPolicy, IIRC, this was changed in 1.0.
