default Set<Bundle> completeBundleGeneration(GenerationStatus status) {
        return Set.of();
    }
If the current generation is a success, the set of bundles that is not needed by the new application
generation, and therefore should be scheduled for uninstalling, is returned.
If the current generation is a failure, all state related to application bundles is reverted to
the previous generation. The set of bundles that was exclusively needed by the new generation,
and therefore should be scheduled for uninstalling, is returned.

@param status The success or failure of the new generation
@return The set of bundles that are no longer needed by the new or latest good generation.
