I think there are a bunch of things that are stale.
For example..."Nova uses Kombu to connect to the RabbitMQ environment." As far as I know nova no longer directly uses Kombu, instead it uses oslo.messaging (which may in turn use kombu but nova doesn't know about it). This means that many of the parameters documented for kombu (like "routing_key" and "durable" and "exchange_type") are no longer applicable.
Similarly, the "delivery_mode" parameter doesn't seem to be relevent to nova anymore.
