Comment (by mkae):

 Actually I'd be for leaving the default setting in place, so that users
 have the original Qt'ish look and feel. If they don't like they can use
 another style or complain at Qt's issue tracker about what should be
 improved. If we replace it here with your tweaked one we'd inhibit this
 (potentially useful and important) information flow.
