Actually using 13 bits out of 128 for IPv6 (a /35 subTLA with a /48 minimum
customer assignment) for a (global) ISP´s reservation, architecture and
hierarchy, when customers get 80 bits for a dozen or less machines would seem
to be based on hallucination and certainly not reality.

It is a good thing the IETF say they are revisiting this - I just hope the
outcome *is* based on reality.

Could Randy (and others) please indicate why he appears to insist on the
smallest possible assignment, at the risk of later needing either a multiple
announcement or renumbering ?

I find it hard to think that IPv6 addresses are in short supply when we
have decided on a /48 mimimum assignment to end users.

Cheers
