Comment 1 for bug 1979816

We discussed this RFE on the last Drivers meeting:
https://meetings.opendev.org/meetings/neutron_drivers/2022/neutron_drivers.2022-07-08-14.00.log.html#l-54

The agreement was to have a spec where the current implementation's differences from the original spec (https://specs.openstack.org/openstack/neutron-specs/specs/newton/fwaas-api-2.0.html ) are listed and the details for the fix can be discussed.
