The migration to post-quantum cryptosystems is a different issue than standardizing one in the first place, and I'm not going to pretend to know anything about the organizational cat-herding needed to achieve such a migration. The US government is beating the drum to have the migration of critical systems completed by 2030, and there are plenty of IT consulting firms who will happily sell post-quantum migration services to get ahead of that deadline. If you're worried about pre-harvested ciphertext that nation-states are sitting on, waiting for the right hardware to come along to decrypt it, I personally have no solution. The genie's probably out of the bottle on that one. Hopefully the affected parties took, or are taking mitigating actions.
