Cogent is its own little fractured IPv6 world. If you're relying on them as your sole transit provider, you will likely never have a "complete" view of the IPv6 Internet. This is true for all single-homed networks, but it's even more true if you're single-homed to Cogent. Also, Google adding AAAAs to their hostnames won't change Cogent wanting to turn peers into customers by shutting off peering connections. This (now removed) news post on ESnet's website when they were depeered by Cogent is pretty telling, especially the bit about Cogent lying to their own customers about the nature of ESnet's unreachability: http://web.archive.org/web/20110610220320/http://es.net/news-and-publications/esnet-news/2011/important-status-announcement-regarding-cogent-connectivity/ http://web.archive.org/web/20110610220320/http://es.net/news... If you want to see this attitude change, vote with your wallet -- stop purchasing transit from Cogent, and then tell your former Cogent sales rep exactly why you're no longer purchasing transit from them. Until their bottom line is impacted, they have no incentive to change.
