This looks good. We'll have to also make sure:

• there's ever only one active SSE per token
• if the SSE connects late, we should flush the subscription messages that emitted before
• this supports just the single connection mode (and therefore both modes with #2445), should we rename the package? or maybe ship it with the core?
