Are you aware you're talking to the guy who added virtual threads to the JVM? Disagree on design if you wish, but the idea he isn't an expert in these matters is a bit silly.
He is person on salary in oracle, which is not top tier tech company.
There are tons of virtual threads like frameworks were implemented in JVM and in other languages, looking at his github profile he has 5 years experience in working on this thread stuff, before that he worked on some bloated j2ee stuff, all of these doesn't qualify for some unconditional authority, so I judge him base on his expertise demonstrated in this discussion, which looks very weak.
