those attributes are shared by neighbor and bridge code for example.
nda_policy should reject it, and a new attribute provides a means for
starting strict checking (add NDA_UNSPEC with .strict_start_type =
NDA_NH_ID).
Similar for the fdb code in rtnetlink.c. Shame AF_BRIDGE parsing does
not have a policy attribute.
