   @jberstler There are many scenarios that it will not be possible for the action to logs
the failed messages e.g. an out-of-memory exception will terminate the action process before
it even starts, a network connection issue will prevent the action from initiating, etc.
   
   Without support for at-least-once delivery, this package cannot be used for any use case
where data integrity is critical.
   
   Even a mediator which receives all the messages from the event and then compares them to
the messages successfully processed by the actions is not completely reliable, as the messages
might fail to reach the comparison queue of the mediator for the same reasons that they will
fail to reach the logging of the actions.
