Saw this news as well. It's probably worth noting that unless something has changed in quantum land, no cryptosystem has ever, or will ever, ship with a mathematic proof that it is secure... except for XOR with RNG. Thus quantum computers and further academic exploits against both non-pqc and pqc cryptosystems may happen someday, typically when least expected. These pqc-enabled cryptosystems are very early. They have received very little academic analysis in comparison to the volumes and decades of work done against legacy systems. And being new libraries, they'll be full of implementation bugs and exploits, and user facing gotchas. Further, the Government, Academic, and Corporate sponsored "competitions" and "standards" bodies... from which many of these cryptosystems have spawned from and been submitted to for judging and "certification"... have been known to be compromised by nefarious agents in the past. And many of these cryptosystems have been authored solely by, or by those affiliated through various [back]doors, with Government and Corporate exploiters and banners of crypto... NSA, GCHQ, IBM, political entities, etc. Choose among whichever the worldwide academic consensus has held out as the best for many years. If using the early days of pqc-enabled crypto apps worries people, you can always compose non-pqc within pqc. GovCorp will never expose its biggest exploits. And in the end, it's rarely the crypto that fails you.
