We only discussed about the large effort needed for the new policies. https://specs.openstack.org/openstack/nova-specs/specs/ussuri/approved/polic... https://review.opendev.org/#/q/topic:bp/policy-defaults-refresh+(status:open...) We asked the Keystone team to review the first changes in the series as it's very helpful. We had concerns about completion over the Ussuri cycle since the series can be very large and we want to avoid deprecation messages for some APIs if not all the Nova APIs are touched yet. The agreement was to hold a procedural -2 on the API changes and start reviewing (for both Keystone and Nova folks) until all the changes are there. Maybe a runway could help once all the API changes are uploaded. -S
