Will Magic Leap be integrated into Unity's XR API?. https://docs.unity3d.com/Manual/XR.html It would make porting things to magic leap so easy.
I am pretty certain, it is utilizing certain elements of the XR API. Also at Leap Con a few weeks ago, they announced ML will be part of the main version of Unity with 2019.1 (If I remember correctly). At that point, I assume they will be merging the api's a good bit. Hopefully.
