Right, except eventsource is pretty simple to pollyfill because it’s just http.

Websockets requires explicit support on the backend, in every layer of your http stack that it’ll traverse.

If the goal is to simplify your stack, websockets is not the solution.

Oh, I agree, and under normal circumstances EventSource + polyfill is what I'd use too. I'm just pointing out that it's not always as simple as overhyped things being used only because of the hype, because sometimes there are genuine technical differences in areas like compatibility or performance as well.
