The fact that the SSE connection is unidirectional makes it impossible to quickly and efficiently detect disconnection from the server-side; this costs extra in terms of performance.

Also, SSEs make it essentially impossible to implement features like real-time user online/offline presence and automatic renewal of authentication tokens (without closing the previous real-time/SSE connection).

Good points about the limitations - SSE certainly won't be useful for lots of scenarios and you might prefer resorting to traditional approaches in those scenarios (in lieu of or in concert with an SSE channel).
