Sir, this is a Wendy's. We're talking about ECH. Can you maybe rephrase all this to be specifically about how DNS record integrity practically impacts the threat model for ECH? The threat actor for Encrypted Client Hello is ISPs.

This same thing happened with DNS cache corruption; which went unaddressed from the mid-1990s to 2008 despite the known fix of port/ID randomization because the DNS operator community was fixated on the "real" fix of... DNS record integrity.
