Another reminder of how eagerly I await Xposed / Xprivacy on ART for 5.0... that said, his examples are fairly benign, I agree that if your app needs to initiate a call, it should show me the dialer to see if I would like to do that now, or some other time (including never).
If you're just waiting for permission controls, App Ops [1] should work just fine on 5.0. There are other comparable apps that also don't require Xposed.
