I understand he was referring to a different API than the one discussed. My question is if the API change he was referring to is still being implemented in Manifest v3 (I've edited my comment accordingly).
I don't think Google has said when extensions with Manifest V2 will no longer work. And, technically, you can still use the blocking webrequest in a Manifest V3 extension, if the extension is "force installed". I think they are waiting for the hoopla to die down a bit before they close the door hard.
