  Yeah, I thought they knew. Here's what I thought might've been on their list 1. You get a single IPv6 per instance (as opposed to a CIDR range). 2. You still have to deal with IPv4 CIDR ranges 3. ...which means you have to deal with all the overlaps still :( IMO I would love it if my ec2 instances were IPv6 only, and then use public IPv4 addresses or dual stack loadbalancers as necessary for public ingress.
