Introduced in branch/version: 10.3.x / 10.3.0

To be able to differentiate between serializers like JSON or YAML which cannot serialize classed PHP objects, and serializers that can (eg. the PHP serializer),\Drupal\Component\Serialization\ObjectAwareSerializationInterface has been introduced. This interface can be used in type-hints or instanceof checks where object-serialization is required to make sure the right kind of serializer is passed.
