" see a potential result of huge swathes of v4 resources reusable by these companies, probably dwarfing the reclaimable resources most any other provider without a similar customer profile will have."
See this is at the hub of it as well, is it a reusable resource, or is it an obsolete one? Should it be getting resused for multi-homeing or content providers, or should it be retired by the ISP that has migrated their subs onto v6? I think if we continue with a mind set that v4 is a previous resource and once I have freed it up by moving to v6 I must hang onto it and of course if I have got some free I best deploy it again for a new customer - this seems completely circular to me. I think the question is: 1> Are we attempting to migrate from IPv4 to IPv6 and end up at a place ultimately where IPv4 is fully intended to be retired. Or 2> Are we simply intending to extend the address space with IPv6 and continue to pretty much carry on business as normal with existing IPv4 deployments in any meaningly foreseeable time frame and run a dual stack network. Further more that it is ok to reutilize any free up IPv4 space along the way as we are never planning on retiring it anyway. I personally think it should be the first of those, but my opinion doesn't really count for squat. Ultimately I would rather we be clear about what we are wishing / aspiring / trying to achieve and then set about achieving it collectively. If the collective view is that it is not a migration but a co-existence that we are aiming for then ok, lets stop pretending otherwise, if however the collective direction is migration then can we please collectively do our best to facilitate and encourage the migration. As opposed to having various tactics to drag out the migration as long as possible as some think that if they drag their feet in perpetuity that the v4 to v6 bridging magic will become the duty of the service provider to make it work for content providers and subscribers that don't want to update CPE routers or rewrite code where nessacery. If we, as a community of operators are going to get on and deploy IPv6 and we agree it's a migration the lets get doing and set some targets dates / BCP for when it is reasonably expected that net/sys admins will have completed the rollout and by whatever contractual or commercial / technical means migrated their customers. If, however, we as a community don't want migration but cohabitation then lets do that. Which one do we ultimately want?
