... and an extra attack (if you happen to have RA-guard but no protection for DHCP). Maybe not that much of a difference, but still a thing to take note of. The extra traffic is a little more interesting in constrained node/networks (e.g., 6LoWPAN). I think we will continue to use the M bit for gating DHCP. (See section 3.2 of draft-ietf-6lowpan-nd-15.txt for details of how we do this.) Maybe our needs are not relevant for the ND-classic spec, but this is just one more data point.
