Hi Scott: I think it is really premature to speculate on features PQ-secure algorithms can or cannot provide (*) and try and have this influence *current* TLS1.3 protocol design. Should one wish to include PQ algorithms in a future update of TLS1.3, one can simply specify which protocol ingr

I'm not precisely sure what you are really saying. Are you claiming that, even though currently known PQ key exchange don't give all the flexibility that (EC)DH has, you're pretty sure that'll change in the future? Or, are you saying that relying on the full flexibility of (EC)DH isn't a probl
