The problem with peer-groups is that today's high end routers don't generate updates to peer-groups. Peer-groups are only a convenience for configuration. High end routers group peers automatically into update groups and generate updates to the update group. Even update groups have sub divisions to which the generated updates may or may not be copied to. This is done for efficient update generation with thousands of peers.
