It is.

Your clients can connect to any node in the cluster and use it: publish and consume messages,
create queues, etc. If a queue can be created on any node, then it's natural to distribute
policies, no?

Because of this, certain amount of cluster state is automatically propagated to all cluster nodes.
Without this, clients would have to know what node exactly they are talking to and that's
significantly less convenient, especially if you take things such as load balancers into
the picture.
