Moin,

as i already said at the mic, I am happy to help; I currently do not
have ICMP related drafts of my own, but some things i am passionate
about (RFC8950/v4-with-v6-nexthop) would really benefit from some of
those drafts making progress.

Yes, I agree on that (and iirc also said sth. along those lines on the
mic); There is a tendency of new proposals to suggest adding state
keeping, which would just be a DoS waiting to happen.

With best regards,
Tobias
