User impact is following: after failover of some controller node, RabbitMQ cluster could be rebuilt and run without some live controllers, which means that high availability of AMQP could be broken. For example:
1) Cloud has 5 controller nodes
2) One controller node goes down
3) RabbitMQ cluster re-assembles, but service is running only on one controller
4) Controller node with alive RabbitMQ goes down
Result: AMQP messages are lost, some cloud operations failed
