Usage of queue.xml in Magento 2.4.x?

In my RabbitMQ implementation, I’ve been working with the following XML files:

• communication.xml
• queue_topology.xml
• queue_consumer.xml
• queue_publisher.xml

However, I recently came across another file, queue.xml.

Can anyone explain what the purpose of queue.xml is and how it fits into the RabbitMQ setup?
