SSE are really a subset of Comet-Stream (eternal HTTP response with Transfer-Encoding: chunked) only they use a header (Accept: text/event-stream) and wraps the chunks with "data:" and "\n\n".

But yes it's the superior (simplest, most robust, most performant and scalable) way to do real-time for eternity.

The browser is dead, but SSE will keep on doing work for native apps.
