I think this is one too many. Especially is there is a variable that the

this as a potential source of calls to the tech support.
I'm ok with "globall routable WAN IPv6 address" being the default. My only
request is that the "link-local only WAN" and "assign loopback address for
management from DHCPv6 PD block"-model is a SHOULD requirement in the
Choosing between the 2 modes, I would favor the numbered one. The reason is
that we still have customers who attach a single PC to their cable modem.
Those device would be just as happy with a single DHCPv6 assigned address.
The service I have in mind would require the customer to have a router,
otherwise they'll have to purchase a different service.
Basically what I envision is that for single PC deployment we'd run
tunneling (6to4) or equivalent, and "customer has a proper CPE router"
would be native IPv6. Single PC is ok to have tunneled as there will be no
multicast etc in that service. For routed multicast IPv6 you really really
want to have a CPE router (at least that is my opinion).
I am also looking at this in the 5-10 year future, where I think all
customers want to have a routed CPE in their home and have multiple
subnets. Not including "link-local WAN" in the model is too short-sighted
for me, even though I can understand why people are hesitant about it in
the short term.
