Comment (by peterwilsoncc):

 Within core `wp_publish_post()` is only called from
 `check_and_publish_future_post()`, it lacks two features of
 `wp_update_post()` and `wp_insert_post()`:

 * `post_updated` does not fire
 * `wp_post->date_modified` does not change
 * `wp_post->date_modified_gmt` does not change

 My educated guess is it's by design and publishing a scheduled post is not
 considered an update per se.

 A number of suitable actions are fired in `wp_transition_post_status()`,
 my inclination is to leave `wp_publish_post()` unchanged.
