Test simply adding a views_data handler class for menu_link_content

Problem/Motivation

In a project I just found the following snippet:

/**
 * Implements hook_entity_type_alter to add views menu-link support.
 *
 * @return void
 */
function MY_MODULE_entity_type_alter(array &$entity_types)
{
  /** @var \Drupal\Core\Entity\EntityTypeInterface $menu_link_content */
  $menu_link_content = $entity_types['menu_link_content'];
  if (!$menu_link_content->hasHandlerClass('views_data')) {
    $menu_link_content->setHandlerClass('views_data', 'Drupal\views\EntityViewsData');
  }
}

Maybe that would be a helpful first step here? I didn't take a deeper look yet, if it really works and successfully exposes the fields in views. Guess maybe the relation is still missing then?
