Richacl is intended to be a common ACL implementation for different protocols. When Gluster supports richacl, it should become much easier to apply the same ACLs over FUSE, Samba, NFS and other access protocols.
This didnt make it for GlusterFS 3.8, moving out of the tracking tree.

The issue is now open in github for the feature @ https://github.com/gluster/glusterfs/issues/225 Closing as 'NOTABUG' as this is a feature.
