That does not make sense. Like X448 we will allow creation of Kyber
(ML-KEM+ECC) only with v5 key packets.

> and/or signing? Or do you see PQC as a v5-only thing, like X448?

Signing is for now not an important topic.  The primary goal is to
secure data at rest (sniffed) to be prepared for the case that classical
encrypion algorithms are at risk due to QC.
