Section 4.3 (IPv6-only core) makes sense, if you define "core" as
"customer edge to peering edge."  ISPs won't save much IPv4 address
space by numbering their core routers into IPv6, but if they assign IPv6
addresses to Dual-stack Lite routers and LSNs, they have a transition
plan.  I can't say whether it's a viable plan, but it's a plan.

I think that's exactly the scenario it describes.  IPv6 plus an 
IPv4-stretcher (NAT444, DS-Lite) is the crustimony proseedcake.
