Whether ended is fired must definitely not depend on when GC happens. GC
timing causing observable behavior changes is anathema.

The answer to your first question is less clear. The question itself is
also ambiguous: do you mean "not directly connected to an output" or "not
indirectly connected to a DestinationNode or MediaStreamAudioSourceNode"?
You'd also have to resolve *when* exactly the graph connectivity check is
performed. In any case, the simplest API is to fire the event no matter
what, and that's what Gecko does.
