the real point is not ipv6 (or this or that specific service). the point is the attitude.
anybody in this subthread bikeshedding what aws service supports what version of the ip protocol has missed the point and would probably fail a text comprehension test.
Nobody missed the point. The examples of AWS after 15 years still being dragged into full IPv6, is to show the lack of support for IPv6, is not the lack of technical awareness that is trying to be demonstrated.
Depending on the context, and granted, lacking some of the subtle details missing in the interaction described, might actually show real experience in the field.
