+| Deletion behaviour                |   ⚠️    | A finalizer ensures the Service Provider managed resources like Flux' `OCIRepository` and `HelmRelease` are cleaned-up. But there is no behaviour that ensures deletion is blocked if custom resources (e.g. Flux' `GitRepository` objects) in a `ControlPlane` still exist. |
