Public bug reported:

Here it can be seen that agents are notified of network delete event:
https://github.com/openstack/neutron/blob/8.0.0.0b2/neutron/plugins/ml2/rpc.py#L304

But on the agent side only network update events are being listened:
https://github.com/openstack/neutron/blob/8.0.0.0b2/neutron/plugins/ml2/drivers/openvswitch/agent/ovs_neutron_agent.py#L374

That was uncovered during testing of Pika driver, because it does not
allow to send messages to queues which do not exist, unlike current
Rabbit (Kombu) driver. That behaviour will probably be changed in Pika
driver, but still it is worthy to get rid of unnecessary notifications
on Neutron side.
