Why are we even discussing this? It's a policy decision for each vendor
and each provider. The arguments are different in different legal, political
and social environments, and they are not specific to IPv6.

There are of course recommended defaults in RFC 6092 and more coming
in draft-ietf-v6ops-ipv6-cpe-router-bis.

Hopefully every provider states what they are doing, as per RFC 4084.
