If you keep this as class NodeCustomEvent extends CustomEvent {}, that might even be a bit nicer since it’s a way to differentiate between events coming from a user and events coming from a Node.js EventEmitter .emit() call?

Could you help me understand what specific usercase do we need to support? I don't understand in which scenario we would need to differentiate between events coming from a user and events coming from a Node.js EventEmitter .emit() call.

constructor(type, options) {
super(type, options);
if (options?.detail) {
this.detail = options.detail;
}
}
}

// Weak listener cleanup
// This has to be lazy for snapshots to work
let weakListenersState = null;
