UI Paradigms for Polyspatial - Colliders or just Unity UI (?)

I notice the examples continue to use colliders for buttons instead of just regular Unity/TextMesh UI Buttons… Going forward, will traditional Unity UI buttons be supported, or will this be deprecated to the collider-based SpatialUI Buttons?

The next release should have a uGUI scene that replaces the spatial UI scene and we’ll be moving towards using more traditional (uGUI) Unity UI buttons.
