+Warning: `Pending publication` is allowed here to handle the edge case of the app thinking data was sent to SQS, but the data not arriving for whatever reason. This is not a normal occurrence, and it is possible to send multiple copies of a single thesis to the publishing queue with this feature.
+
+Please be sure the SQS queues are fully processed, and that you are absolutely confident that sending a `Pending publication` status thesis back into the publishing queue is appropriate. Failure to use care could lead to a single thesis being published more than once. This would result in multiple handles and DSpace records, and could cause confusion for end users and processing staff.
+
+This is only a concern specifically for the `Pending publication` and `Publication review` statuses as no other statuses can be sent to the queue with this method.
