> Currently, an application using explicit acknowledgement which neglects to acknowledge all of the records received from calling `poll(Duration)` is re-presented with the records on the next call to poll. This has been shown to be confusing.
> An option will be added, initially experimentally, to throw an exception on poll instead. If the experiment is successful, this will become the new behaviour.
