Is the question under discussion whether to document what has already been implemented? If so, then discussion of the merits/demerits is indeed academic -- but so is discussion of adoption of the document as an IETF WG work item. Just put the documentation on a web site, or send it to the RFC Editor for publication as an Independent Submission.

Or is the question whether the document is an appropriate basis for future work? If so, then discussion of merits/demerits is not at all academic -- it is a core issue.

This part of the thread was not about DHCP Authentication but the relay behaviour in broadband networks. Basically current behaviour is to do a Radius Access Request on the DHCP discover and fill in information from the Access Response into the DHCP Offer. Now in some cases IP address comes from the AAA server or the DHCP Discover is relayed to a DHCP server and then we have the situation that information from the Access Request can be "inserted" in at what is a type of a relay function and their was repeatedly expressed concern from Alper at that.

It has become clear to many folk that this is not written up in the IETF and in some conversations we had post this mornings WG meeting Peter Arberg from Redback has kindly offered to start a write it up from the DSL community so the behaviour of this function can be documented, independent of the fate of the Subscriber Authentication proposals.
