No one is ignoring it, and the US Government has done everyone another favour on this score. Years ago in the late Bush / early Obama administration, NIST required that all federal government agencies have IPv6 at the border. Federal government money is not to be sniffed at, and that had the effect of forcing a number of vendors to add IPv6 support. A few years after that, it became that the federal agencies needed to have dual-stack IPv4/IPv6.

About 18 months ago, the requirement came that federal agencies are required to be IPv6 Only, dropping the dual stack. IIRC they have until 2025 to do that. This has the neat effect of forcing all vendors to make IPv6 a first class citizen. The extra little fun from this is that it applies to the military JWCC contract that all the major clouds have been trying to land. The timescales of JWCC meant that initial offerings are pretty bare, but that won't be allowed to last.

Yep.

I work a federal entity tied to DoE and that's the biggest workstream cut out for us. 90% of our environment is either dual stacked or IPv6 native. We would love to kick IPv4 out under us and go full IPv6. Problem is that the vendors who are largely private don't have the same mandate so there's varying degree of "we support IPv6" which makes planning bit more difficult (especially at the discovery stage).

They get to decide how much that sweet federal $$$$ is worth to them. For most vendors, it's hopefully worth too much to ignore.
