> * We can introduce something like *Tuple.tombstone* method to indicate removal through the Flow.Publisher API. But this won't work with POJOs
> * Alternatively, wrap every item: instead of *Flow.Publisher<T>* the API will accept *Flow.Publisher<StreamerItem<T>>*, which can be used like *publisher.submit(StreamerItem.ofDeleted(new PersonPojo(...)))*
