The government has a poor track record of pushing a technology in this space. They’ve been mandating ipv6 in the dod for - gosh at least since 2008 or so.
Oh, and you have the government to thank for the useless posix subsystem for windows back in the 90s (remember that?) as a way to force software “interoperability” between Unix and windows. Companies vying for federal contracts will look at the poorly defined requirements and find a way to just barely meet the letter but not the spirit.
"THOU SHALT USE IPV6 BY XXXX date or you don't get subsidies and/or lose spectrum and/or lose IPV4 ranges".
This is not designing a new complicated api compatibility. ALLEGEDLY the ipv6 geniuses have everything figured out technically. There is ALLEGEDLY no protocol development, RFC, standards body formation. ALLEGEDLY it's all been laid out. There are some success stories, there are "reference implementations" in production.
Again, it's not like this is hard to disseminate to the necessary powers that be. America is a bunch of monopolies and cartels. That means the regulatory agencies can call like 10 people and tell them the lay of the land. This is not herding a thousand cats with a fork, this is using shock treatment on elephants.
