This work has been in development for almost a decade. This particular
approach started in 2013. Let's not restart the work until we exhaust
all other possible alternatives.

How about the proposal Bernie made here?
https://mailarchive.ietf.org/arch/msg/dhcwg/c2bB8KdbGgsZShHtnyUgKwELa-w

Another possible approach to the problem mentioned in off-line
discussion was DTLS 1.2 (RFC6347), but Francis pointed out that it's
quite exchange heavy, compared to DHCP, which takes 1 or 2 exchanges.
Going to 3 or perhaps 4 exchanges is ok in my opinion, but if the
proposal requires more than that, we would see a lot of raised eyebrows.
