Not too hard to fallback; but on this note, do we maintain minimal OVN version anywhere in neutron? I remember when I was adding support for allow-stateless ACLs, I was told we don't track it (hence runtime schema inspection in https://review.opendev.org/c/openstack/neutron/+/789974) Considering potential backports in downstream products, perhaps a runtime schema check is a better approach anyway.

To close the loop, the patch that uses stateless dnat_and_snat has merged in master. Including migration path for existing NAT objects in nbdb and runtime check for core OVN support. Probably not a backport material for upstream. Ihar
