It looks like the general recommendation about SSE is to send messages at fixed interval to clients to probe the connection health (see #18523 (comment)).

Could Spring add this feature?

Add tests for SSE heartbeat (ping) functionality
2b7db6e 
This commit adds test cases to verify the heartbeat (ping) feature in SseEmitter. The tests ensure that heartbeat messages are sent at the specified interval and that they stop after the emitter is completed.

Add heartbeat (ping) functionality to SseEmitter
0bf3e44 
This commit introduces the heartbeat (ping) feature in SseEmitter. It allows the server to send periodic heartbeat messages to the client at a specified interval to keep the connection alive and detect client disconnects. Heartbeat messages are sent as comments (":heartbeat") and stop when the emitter is completed, times out, or encounters an error.
