    Feedback: The function name does not seem to indicate that it does not do the usual actions expected from transitioning a post to publish status. The note inside “more information” is easy to miss.

    Can the following note be moved from more information to the main description?
    This function does not do anything except transition the post status. If you want to ensure post_name is set, use wp_update_post() instead.

    P.S. Just a thought (I don’t have the full context), if the function is only supposed to be used when publishing a future post then consider deprecating this and creating a new one called `wp_publish_future_post`?
