A single /64 would, currently, be sufficient for 99% of households. The
link can be /128, /127, /64, whatever -- between ISP and CPE doesn't
matter to the customer. (maybe to their equipment) As this is being done
via DHCPv6-PD, it's a simple matter to ask for more space (typically /60)
in the rare cases the customer needs it. And in a decade when 16 LANs
isn't enough, allow /56's.
If it weren't for stupid SLAAC and it's nanolathed-in-diamond prefix===64
requirement, we could start out - day one - with more reasonable sizes.
Give everyone their own entire internet (::/96) to carve up as they wish.
It's not like anything even on the whiteboard today can handle a fraction
of that many devices in a single LAN.
