+[kubeadm-kinder-learner-mode-latest](https://testgrid.k8s.io/sig-cluster-lifecycle-kubeadm#kubeadm-kinder-learner-mode-latest) was added as part of the [kubeadm dashboard](https://k8s-testgrid.appspot.com/sig-cluster-lifecycle-kubeadm) since v1.27. All tests in this dashboard use the [kinder](https://github.com/kubernetes/kubeadm/tree/main/kinder) tool.
 
 - During Alpha (disabled by default): add a new e2e test that enables the feature gate EtcdLearnerMode
 - During Beta (enabled by default): modify the e2e test to test the feature gate EtcdLearnerMode as disabled
 - During GA (locked to enabled): remove the e2e test as the logic will be exercised in all existing kubeadm e2e tests
