GCP doesn't really support IPv6 at all. Sure you can terminate IPv6 on a load balancer and then proxy the connections over IPv4 back to your instances, but you can't get native IPv6 on an instance.

It's that type of shortcoming that leads me to believe Google does not see a future in this product.

The network virtualization scheme and likely many other parts of the stack need to change in order to support v6. It's not that there aren't investments in this area, it's just a non-trivial effort.

Were they surprised that IPv6 existed? It's not as though this is a new technology, or that the necessity hasn't been obvious since around the time Google was born.

It takes longer to climb a hill if you start by digging a hole.

I’m on ipv6 at home and aws is finally pretty good on IPv6 for me - security groups / vpc/ instances - is a very nice feeling
