the problem is multiple tabs. if you have, e.g. a bunch of Grafana dashboards open on multiple screens in different tabs (on same domain), you will exhaust your HTTP connection limit very quickly with SSE.

in most cases this is not a concern, but in some cases it is.

Aha, ok yes then you would need to have many subdomains?

Or make your own tab system inside one browser tab.

I can see why that is a problem for some.
