This is a dense article but what seems reasonably clear is that someone is pushing hard for an insecure standard.

There’s no reason at this point to put all your cryptographic eggs in the post-quantum crypto (PQC) basket. Elliptic curve crypto (ECC) is widely studied and understood; while it’s more vulnerable to quantum cryptanalysis, this is mitigated by the hybrid ECC+PQC proposals (except a bit of lost performance). On the flip side, the PQC stuff is new enough that new attacks are still being devised, so relying fully on that seems like a bad idea. Someone is trying to force the standardization of a PQC-only standard under the claim that it is secure enough, but ignores evidence from quite recent work showing that attacks continue to improve. This is before getting into the fact that PQC implementations are harder to get right and that popular PQC implementations have had nasty side-channel attacks.
