Moreover, it has undergone breaking changes and is no longer functioning as intended. As a result, this tool, which heavily relies on the Controller Runtime, has also deprecated this feature, no longer guaranteeing its functionality from version 3.11.0 onwards. You can find additional details on https://github.com/kubernetes-sigs/controller-runtime/issues/895.
