Maybe one of the reason why it become unpopular is the additional code you have to implement with asynchronous processing in a separate system and tracking in case of errors during processing in the target system.
Its easier and faster to make a Webservice request where you get an instant result you can handle directly in the source System.
Mostly the queue is implemented in the source System where you can monitor and see the processing status in Realtime without delays.
