Abe mentions "more efficient and productive use of our resources" and I think we all wish for that.

I think this WG should discuss the general question whether the minor wastage of IPv4 address space that this set of drafts addresses is an efficient and productive use of our resources. In other words, where are we with respect to conditions (1) - (5) in the WG charter (https://datatracker.ietf.org/wg/intarea/about/)?

Incidentally, the WG milestones look a bit OBE.

Regards

In studying this lead, I discovered that there are at least a few similar ongoing IETF Drafts being proposed by the "IPv4 Unicast 
Extensions Project":
