Can we use that shortened syntax? I've been suggested that usage of such short amqp url forces rabbitmq to work in "direct" mode, which is more efficient. However, when I changed my local connections settings for shovels like that, I don't see those connections in connections list anymore.
Take a look here:

Specifically:
If the host is omitted (not valid in a general AMQP URI), the shovel uses a direct connection to the broker in which it is running. This avoids using the network stack
