I think that I said we didn't need it.
That all we need is to become aware of the neighbours (which insecure DULL
can do with M_FLOOD), and that all the security is best done by IKEv2.
(And IKEv2, even if MacSEC is negotiated rather than IPsec)

The ACP-04 document imagines a protocol that isn't IKEv2 using some
unspecified encapsulation over (d)TLS transporting IP packets, and negotiated
using GRASP.  This hardly has any existing specification (one in tsvwg right
now), and has no hardware support anywhere.  It's not our place in this WG
to create new security protocols.
