We may want to name the option to something more explicit like deletion-policy with possible values owner / ownerReference or label / labelSelector to fit into k8s garbage collection scheme.

I wonder whether we should check the foregroundDeletion finalizer and emulate a background cascading deletion when no present by removing our finaliser first and then delete the child resources.

I think the logic should be reverse. In background cascading deletion, Kubernetes deletes the owner object immediately and the garbage collector then deletes the dependents in the background.

I wonder whether we should deactivate cascading in the delete operation so that we fully rely on the label deletion policy and avoid mixing label and owner strategies and get rid of these special cases.

We could set the PropagationPolicy to orphan here.
