You are right - there’s no urgency in PQ signatures. However, PQ KEM keys aren’t small. And, as I said, für austere links every unnecessary byte of crap hurts. Also, sending root certs seems (marginally) useful only when the recipient is a Web browser. And even then I assume most of the IT p

For a Web GUI with the user at the console (e.g., a Web browser), it might be OK. For my needs (devices talking to each other over austere links), sending the root CA very is both useless and wasteful. One you factor in the sizes of Post-Quantum keys and signatures - you’ll start disliking thi
