Do you know this, or is this a guess? This would be surprising to me. Suppose Amazon acquires an architecture license, designs a custom core for Graviton3, and deploys it in AWS. Could they add custom instructions at will? I would think ARM would be very unhappy when there are applications that run on amazon's arm64 CPU that don't run on ARM's arm64 CPUs, and I would imagine that that would be reflected in the license terms.
