What specific section or headline is this issue about?

No response

What information was incorrect, unhelpful, or incomplete?

I was sent here by this runtime message, which is the first I've heard of it:
Returning a Promise is the preferred way to send a reply from an onMessage/onMessageExternal listener, as the sendResponse will be removed from the specs (See https://developer.mozilla.org/docs/Mozilla/Add-ons/WebExtensions/API/runtime/onMessage)

I go to that page, and there is not one mention of sendResponse being removed or deprecated.

What did you expect to see?

a mention of sendResponse being removed or deprecated.

Do you have any supporting links, references, or citations?

No response

Do you have anything more you want to share?

@TheDirigible it appears that this message is coming from the polyfill and there is an outstanding ticket mozilla/webextension-polyfill#386 to address this.
