The W3C citations on MDN are a historical artifact by the documentation folks, not influenced by the browser folks. There's a slow movement to consolidate around what's implemented and stop referencing W3C forks, and I think today's news will help hurry that along. See e.g. the discussion in https://github.com/mdn/kumascript/issues/1019 https://github.com/mdn/kumascript/issues/1019 or my previous work in https://github.com/mdn/kumascript/pull/220 https://github.com/mdn/kumascript/pull/220.
