> Currently, the API of {{CloseableRegistry}} exposes the {{close}} method to all client code. We should separate the API into a user-facing interface (allowing only for un/registration of {{Closeable}} and a system-facing part that also exposes the {{close}} method. This prevents users from accidentally calling {{close}}, thus closing resources that other callers registered.
