I tried to setup an IPv6-only VPC last month and ran into lots of edge cases. For example, Terraform's aws provider doesn't support the http_protocol_ipv6 metadata option for EC2 instances, you can only set it in a launch template. It's a two year old issue: https://github.com/hashicorp/terraform-provider-aws/issues/2...
I'm glad to see AWS driving people towards IPv6, but the tooling and documentation need to get a lot better.
