Windows Universal App Support?

Hey are universal apps going to be supported? It would make creating cross platform wp8 and windows8 apps much easier, I have been trying to convert monogame to run as a universal app and have succeeded on the windows 8 side of things but cannot get a compiling version of monogame for the phone using the windows phone 8.1 API.

The Windows Phone 8.1 API seems to have removed some things that monogame required, has anyone managed to get a non Silverlight windows phone 8.1 monogame project working? One that uses XAML?
