Shouldn't participant 'create registration' check for allow duplicate contact?

Since events have a column allowing/prohibiting duplicate Event registration per contact, shouldn't 'register new event' and 'register with credit card' (accessible from contact/events) also check that bit, and allow a duplicate registration if event.allow_same_participant_emails is set?  If so, the fix is a couple of lines in Participant.php as below (added line 860, modified line 867):

line 859      $eventId = CRM_Utils_Array::value('event_id', $values);
line 860      $allow_dupe_reg = CRM_Core_DAO::getFieldValue('CRM_Event_DAO_Event', $eventId, 'allow_same_participant_emails');
      //need to get value from event ALLOWING dup - event.allow_same_participant_emails == TRUE
      if (!empty($contactId) && !empty($eventId)) {
        $dupeCheck = new CRM_Event_BAO_Participant();
        $dupeCheck->contact_id = $contactId;
        $dupeCheck->event_id = $eventId;
        $dupeCheck->find(TRUE);
line 867        if (!empty($dupeCheck->id) && !$allow_dupe_reg ) {
