I don't see how such an architectural limitation can be enforced.
There is no way that the IETF can prevent an ISP issuing IPv6
customers a /128 if they choose.
Not directly, but there's the indirect route: a) IETF designs IPv6
autoconfiguration. b) Linksys, D-Link, Netgear and friends make boxes
that support autoconfiguration. c) ISP hand out /128s. d)
Autoconfiguration doesn't work well. e) Customers call ISP support. f)
ISP loses $$$. g) ISP starts issuing /48s instead.
I don't know the first thing about how IPv6 autoconfiguration works. It
worked very well in my previous office. Will it work better when the
router has a /48 at hand than a /64 or /128?
