Comment (by danielbachhuber):

 @pento I don't love using output buffering and regex as a shim, but it
 does give us whitelist control over the behavior. I notice that core
 itself has this, which we wouldn't want to accidentally render:

 {{{
 // Show a "postbox" with the text suggestions for a privacy policy.
 add_action( 'edit_form_after_title', array( 'WP_Privacy_Policy_Content',
 'notice' ) );
 }}}

 > It's likely that `edit_form_after_title` and `edit_form_advanced` could
 both be run after `admin-header.php`, in which case we don't need to pass
 them around like this.

 Do you think this runs the risk of any execution order bugs?
