It's correct observation, Nate.
Linux bridge agent uses this notification to delete network's bridge unlike OVS
agent which only needs port delete notifications.
I think it's not a big deal if notifications are just lost if nobody consumes
them.
Closing as invalid.

Title:
Nobody listens to network delete notifications
Status in neutron:
Invalid
Bug description:
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.
