Inventory_Presser_Template_Provider::maybe_provide_template( string $template )
This method decides whether or not to add filters to the_content and has_post_thumbnail by examining the template file. If the theme does not have templates for vehicle singles and archives, the filters are added and shortcodes provide the templates instead. I stole this technique from WooCommerce, and it’s kind of beautiful.
