Those who wish to use pure PQC do not need permission. This is about IETF 
_endorsement_. 

Endorsement is based on many factors. 

..." by googling "deploy ML-KEM now" and being recommended this rather than a 
safer hybrid[1]. I am not convinced that such a person, if given more 
knowledge, "doesn't want to do that". 

This assumes that “more knowledge” must lead to “don’t do ‘pure’”. Which is 
“purely” wrong – there are several aspects of a solution that contribute to or 
detract from “safety”, and the theoretical truism of “combination of different 
(independent) algorithms is generally stronger” is merely one – not even the 
biggest – part of it. 

Deirdde> As a coauthor on hybrid publications and I-Ds, I do not agree that 
hybrids are categorically safer. The -tls-hybrid-design for hybrids is pretty 
great... if you use secure component algorithms. 

Deirdre is absolutely correct. 

And even when the components are strong now – remember that the key (no pun 
intended) point of this exercise is to deal with CRQC, which will make all of 
the Classic components immediately useless.
