Better way to find objects in QML via C++

Currently in order to find the object under test in qmltest you have to go via objectName. This is a little cumbersome, because it means that your production code is filled with objectNames that have no benefit other than as test hooks. A more elegant solution would be preferable - perhaps QmlTest could find them using a QmlContext and an id? Or there could be a way to find elements declaratively (the first MouseArea in MyApp.qml with an id matching theArea and width:20).
