Consider ServerSentEvents over WebSockets?

I just saw this article https://germano.dev/sse-websockets/ I need to read it a bit more and really understand it, but overall the concept seems fairly straight forward. It made me think.... what if Lucky just implemented SSE out of the box instead of the traditional websocket handler option like I was attempting in https://github.com/luckyframework/lucky/pull/1305 🤔

So far using https://github.com/cable-cr/cable with Lucky has been awesome for websocket usage. I haven't worked on that other PR because there really isn't much of a need, and it's a pretty complex area. But if we could get something built-in that's a lot easier to understand and use, maybe it's a better alternative?

Start by reading the linked SSE-versus-WebSockets article and the discussion in pull request #1305, then review how Lucky currently integrates cable-cr for WebSockets. The issue does not specify an entry point, tests, API, or acceptance criteria, so the intended built-in SSE design and definition of done need to be established first.
