Strange then that they routinely don't wait for and ignore any and all input from other browser vendors and ship their own APIs without any consensus or agreement because "their rigorous process is good" or something.
E.g. almost every single API marked as "experimental" on MDN docs [1] is already shipped in Chrome despite most specs being "not on any standards track", "has multiple issues", "no consensus and API is in flux" or "it is provided for discussion only and may change at any moment."
