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.
Hi, how about Browser Support?

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