@xrobau has been an advocate of IPv6 and made strong pushes for it. Unfortunately it was (probably still is) a low priority considering the heavy North American user base. The US is privileged to own most of the IPv4 space.
Before I left I made a request to get AAAA support for the activation server and other infrastructure and was told it was an edge case and not any time soon.
I always joke that IPv6 is a fad and the cool kids are on IPv10
In any case some things do support IPv6 already and there should be a push to make sure everything does.
