class ContentHubViewSubscriber in Acquia Content Hub 8

View subscriber rendering main content render arrays into responses.

Additional target rendering formats can be defined by adding another service that implements \Drupal\Core\Render\MainContent\MainContentRendererInterface and tagging it as a

render . main_content_renderer;

, then \Drupal\Core\Render\MainContent\MainContentRenderersPass will detect it and use it when appropriate.
