Perch 2.5 apps.php format

When adding the events app to Post-Perch 2.5. docs say to add 'perch_events' to the array in the perch/config/apps.php file to complete the installation like this.

<?php
            $apps_list = array(
                 'content',
             );

However, my (Perch version 2.5.3) apps.php file still uses

<?php
              include(PERCH_PATH.'/core/apps/content/runtime.php');

I assume that just adding it pre 2.5 style is fine?

<?php
    include(PERCH_PATH.'/core/apps/content/runtime.php');
    include(PERCH_PATH.'/core/apps/perch_events/runtime.php');
?>
