Feedback for “Messaging API”

[cdaringe]

Problem statement

My background script must eventually push a message to my content-script, however, the messaging docs don't clearly articulate the pattern. The table suggests "Port + Relay" is the solution, but a recipe is not offered for pushing messages from bgsw to content, only req/res style with ports/relays.

I eventually downgraded to:

      await browser.tabs.sendMessage(details.tabId, { type: "FOO", data });

which is untyped, has no fancy react hooks, etc.
