That looks like it fits with the theme, but events are difficult to compose & tend to have easy leaks by requiring explicit attach/detach (not that I'm sure the proposal here addresses those issues)

Could you not just compose a new EventEmitter constructor that uses the new FinalizationRegistry API to drop all handlers of subjects which have since been garbage collected?
