The flag was removed in upstream Chromium because the feature is enabled by default now: https://chromium-review.googlesource.com/c/chromium/src/+/5100554

@fmarier would it be possible to somehow add the flag back?

Russia recently started blocking all ECH-enabled connections, making numerous websites inaccessible: https://adguard-dns.io/en/blog/encrypted-client-hello-misconceptions-future.html
