Possibly Internet Explorer support. Even Edge doesn't support them yet[1].
With deployments of HTTP/2 increasing, I think we'll see greater adoption of server sent events. At the time of writing, HTTP/2 and WebSockets are two incompatible standards. For non-latency sensitive applications (i.e. not games) it is very easy to implement a WebSocket like interface over HTTP/2 using SSE (server -> client) and POST requests (client -> server) with very little overhead (thanks to HTTP/2's multiplexing).
