Description:
When loading a route in an AJAX context, such as within a dialog or modal dialog, the theme system should load the dialog in the same theme as the underlying page.
In Drupal 7 this was accomplished by declaring the 'theme_callback' => 'ajax_base_page_theme' for each hook_menu() entry.
In previous versions of Drupal 8 this was similarly achieved by adding _theme: ajax_base_page to each route definition.
However, every route should be able to be used in a (modal) dialog, without the route author needing to declare that it is possible beforehand. And this is already made possible by sending the ajax_page_state along with the request.
Therefore this routing option is no longer required.
