I thought the plan was to announce (NOT negotiate) the ability to
decode IPcomp.  You don't need negotiation, because there's no need to
agree on anything.  All that you need is to announce the ability to
decompress, and then the sender can compress accordingly if and when
it chooses.

IKEv1 handled this by negotiation, but 90% of what it does for IPcomp
is unnecessary and confusing.
