説明
In "real", long-running apps, dropping the reference to the materializer is often a sign that you create too many one-off materializers without shutting them down again after use (potential memory leak).
I guess the StreamSupervisor could monitor a reference queue to see when this happens but it's hard to say if it will introduce spurious warnings.
