The benefit of keeping this code around was to inspire or inform changes in the areas to take into account possibly missing features in Qt 5, but at this point that benefit is questionable. We can always use the history to learn about missing pieces if needed. Change-Id: I87a02dc451e9027be9b97554427bf8a1c6b2c025 Reviewed-by: Tor Arne Vestbø <tor.arne.vestbo@qt.io>
