I don't think that standalone ML-DSA should be adopted.

There is time to move to a non-hybrid X.509 and digital signatures in the
future.

This topic has implications to availability of X.509 certificates, as there
is a real risk that CAs will prefer standalone ML-DSA to ethe exclusion of
hybrids, and also that other protocols will be limited to standalone ML-DSA.
