      In 4.12.0-rc.0 some API-server components declare flowcontrol/v1beta1 release manifests:

      $ oc adm release extract --to manifests quay.io/openshift-release-dev/ocp-release:4.12.0-rc.0-x86_64
$ grep -r flowcontrol.apiserver.k8s.io manifests

      The APIs are scheduled for removal in Kube 1.26, which will ship with OpenShift 4.13. We want the 4.12 CVO to move to modern APIs in 4.12, so the APIRemovedInNext.*ReleaseInUse alerts are not firing on 4.12. This ticket tracks removing those manifests, or replacing them with a more modern resource type, or some such. Definition of done is that new 4.13 (and with backports, 4.12) nightlies no longer include flowcontrol.apiserver.k8s.io/v1beta1 manifests.

      This can be noticed in https://gcsweb-ci.apps.ci.l2s4.p1.openshiftapps.com/gcs/origin-ci-test/pr-logs/pull/27560/pull-ci-openshift-origin-master-e2e-gcp-ovn/1593697975584952320/artifacts/e2e-gcp-ovn/openshift-e2e-test/build-log.txt:
