Answer 1

To further answer the original question. Here is how you limit added data for some serialized groups (in this example some_data is only added when we are not using the list group:

public function onPostSerializeSomeEntityJson(ObjectEvent $event) {

    $entity = $event->getObject();

    if (!in_array('list', (array)$event->getContext()->attributes->get('groups'))) {

        $event->getVisitor()->addData('user_access', array(
            'some_data' => 'some_value'
        ));
    }
}

(array)$event->getContext()->attributes->get('groups') contains an array of the used serialized groups.
