      If you enable both finalizers (delete-psmdb-pods-in-order and delete-psmdb-pvc) and delete the CR:
      1. pods will not be deleted in order
      2. you will have some PVCs left (not all but 2 - one from cfg-0 and one for rs0-0)

      Here's how it looks.

      As you can see two PVC are left and pods are not deleted in order.
