Apologies for focusing on a single portion of your argument, but this claim in particular stuck out to me. To my understanding, IETF worried a _lot_ about breaking TLS 1.2 implementations with the TLS 1.3 change, to the point that TLS 1.3 clients and servers advertise themselves as TLS 1.2 and sneak the actual version used into a TLS extension (roughly analogous to the _pq_ stuff). I vaguely recall that the engineering work done for that update was pretty far from painless. --Jacob
