[address-policy-wg] Status of 2011-02 Policy Proposal (Removal of multihomed requirement for IPv6)?

Hi,

this is a repeat for the 68060th time so i try to be brief:

there wasn't a multihoming requirement in the IPv4 PI world lately, or was it?
there is no IPv4 PI problem (rather a IPv4 PA deaggregation problem), so there certainly won't be any with IPv6 PI - by design ("one prefix only, usually")
there is a problem with this difference between IPv4 and IPv6 PI policies which hinders IPv6 deployment right now

This policy change is about NOTHING else than aligning the IPv6 PI policy with
the IPv4 PI policy we have for ages.
It will not end the world or encourage more IPv6 PI usage than IPv4 PI usage. All other requirements
are still the same (roughly).

This policy change does not try to solve any other problem than allowing IPv4 PI holders
who don't multi-home to be able to get IPv6 PI and do the right thing - getting IPv6 deployment started.

If there is a problem with this policy in 5-10 years due to some reasons, we can change the policy again, it's
not written in stone. Things change, policies can, too.
