Admittedly, Internet Explorer and Edge don't support EventSource though they support WebSocket. However, Microsoft insists on using Edge instead of IE, and Edge is in heavy development now. So I think that Edge will support EventSource someday.
Having said that, there might be no person to dare to use EventSource if there were no server restriction for now.

I agree, event source is a feature wich will never be used in production.(from my side exactly)
