We already have way to many algorithms thus if there is an option to
limit them we should take this opportunity.  AES256 is the cipher
algorithm everyone use and it has hardware support.

Twofish was an AES candidate which did not make it.  Camellia was
included for pure political reasons.  Frankly, I am glad that we have
not seen a demand for other national cipher algorithms in the last 20
years (Despite that there are at least a Russian and a Chinese set of
algorithms).

RFC-9980 (the alternative PQC for OpenPGP) actually allows AES-128 with
ML-KEM but uses some wishy-washy language to justify it.
