docs: // HasChildren checks to see if a datastore cluster has any child items
  // (datastores) and returns true if that is the case. This is useful when
  // checking to see if a datastore cluster is safe to delete - destroying a
  // datastore cluster in vSphere destroys *all* children if at all possible
  // (including removing datastores), so extra verification is necessary to
  // prevent accidental removal.
