The "IPv4 CS" doc is the only remaining deliverable and only has one DISCUSS to clear in order to proceed.
I think it's worthwhile doing so in order to have an RFC to document the IETF's position on IPv4 over 802.16
(not necessarily WiMAX). The non-support from NWG (or at least some in NWG) is already known and
taken into consideration in the IESG deliberation process, in spite of which, the IESG has approved
except for the aforementioned DISCUSS (which this version 07 will hopefully clear).

The current plan is to finish publishing IPv4 CS and then shut down the group, given there are no more
deliverables and no energy left in the WG. 

The new developments for newer revisions of 802.16 sound interesting, but this seems like a separate effort.
It may be worthwhile, but that would require an energized community to tackle the necessary re-chartering, 
editing, participating, reviewing, chairing and we have not seen anything near that level of interest for years 
in this WG. Of course, it could be done outside of the WG, but the point is that this feels like a different
document altogether not something that should prevent this last deliverable to be published. 
When and if that new document is published, it may update and/or obsolete some of the current 
16ng documents. This is part of the IETF lifecycle for documents, so there's nothing wrong about that.
