This seems to be more of a request to change the upstream API behavior. You may want to check with upstream Kubernetes on the behavior here.

IIUC you're expecting the pod status to be marked Terminating if the deletion timestamp is set. What did you see before this change?

Also this is generated code, so we should not change it directly.
