As said DNS operator (founder and CTO of DNSFilter.com) - I concur. We’ve been offering DoT for years, but are about to improve the offering with 0-RTT support.
We’re also working on POCs of DoH support, but it’s mostly moot compared to our DoT offerings which cover the whole OS, not just the browser.
Operating systems are going to do DoH (Microsoft already is), and that's going to be the end of it --- browsers, the most important application, are already bought in. DoT is a footnote.
While I truly respect your credentials, I disagree 100% with your conclusion and think DoT will win out. Should be fun to visit this thread in a year, just to see.
