Websockets seems strictly more efficient than this strange attempt to create your own protocol. Not sure what challenges you've had with websockets, but I can't see how SSE is more efficient. Especially when creating protocols like client -> server where you'd need really custom edge proxy configuratings.

Actually it’s not strange at all, we came up with similar architecture that we found our later is much like RAMEN:
