 Yep, exactly this:

 {{{
                         if ( empty( $menu_item->description ) ) {
                                 /**
                                  * Filter a navigation menu item's
 description.
                                  *
                                  * @since 3.0.0
                                  *
                                  * @param string $description The menu
 item description.
                                  */
                                 $menu_item->description = apply_filters(
 'nav_menu_description', wp_trim_words( $menu_item->post_content, 200 ) );
                         }
 }}}

 That's inside of `wp_setup_nav_menu_item`.

 I'm really not sure of how best to handle this, but looking at your latest
 patch in
 https://core.trac.wordpress.org/attachment/ticket/29890/29890.6.diff I'm
 curious why there's no output filter via `nav_menu_description` available
 to `Walker_Nav_Menu`. How would you feel about using `nav_menu_description
 ` in your patch to allow theme developers to filter that output for
 whatever reason?

 For example, if I know that a user is on an old version of WordPress and
 has a ton of trimmed post content stored in his menu descriptions, I could
 modify that output via `nav_menu_description` from within the theme for
 front-end display.
