Your explanation is very valuable and completely correct in my opinion. Nevertheless there are some differences concerning the queuePrefetch between version 5.14.1 and 5.13.3.
The Dispatched Queue contains maximum one message in 5.13.3 with a queuePrefetch of one and that at any point in time. I have a unit test ready which indicate the difference. I can create a Jira issue and share my unit test if you wish ?
