Which thread on which list?  DHCP-PD works to any home gateway that
supports IPv6. I know how the routing is set up in cable, don¹t know about
other access.
Or did you mean a prefix for a mobile device? Ongoing discussion in IETF
v6ops, with consensus that multiple addresses are needed.

There¹s disagreement among ISPs about what size prefix to delegate. So
what? Pick a number and do it. I don¹t know of anybody who thinks a /64 is
right for the home user, but I know of clueful people running every nibble
between /60 and /48. Pick a number, plan so you can change it later, and
deploy.
