Just to be on the same page and that there is no misunderstanding: which 
posts? Preference for hybrids has always been my top concern (e.g., see 
[0]). So nothing has really changed in my position. In fact, that's why 
I isolated the recommendation for hybrids 
(draft-usama-tls-ecdhe-mlkem-update) from deprecation of other 
algorithms, since the latter will take longer.

If we absolutely have to: addressing the concerns in [0] and the ones by 
others mentioned in my email that you are replying to.
