true, but some (most) of them only apply in networks where multicasting/ND is fully supported which is not necessarily the case in the above type of networks.
and, from what I understand, in their scenario RAs are not sent to link-local scope all nodes (ff02::1), so that would eliminate another attack vector (depending on the actual processing of RAs on the CPEs).
