+[failed Pods](/docs/concepts/workloads/pods/pod-lifecycle/#pod-garbage-collection),
+[objects owned by the targeted resource](/docs/concepts/overview/working-with-objects/owners-dependents/),
+[completed Jobs](/docs/concepts/workloads/controllers/ttlafterfinished/), and resources
+that have expired or failed.
