Windows Universal target without Windows 8.0

If I create a cordova-windows project and open it with Visual Studio Express 2013, I get a notice that I have to retarget the project for Windows 8.1. In fact, Windows 8.1 and Windows Phone 8.1 targets already exist, so I have to simply remove the Windows 8.0 target. In addition, I suspect more and more plugins will drop support for Windows 8.0. Can we make the Windows 8.0 target optional or drop it from the Windows Universal target?
