I think the second point is essential. Occlusion is cool, sure, but not terribly important. Right now AR is very limited in what it can do because it can only understand the virtual objects the creators of the app have put in, the world is just arbitrary low resolution meshes. Querying the world would be such a big step. Even just being able to persist annotations on specific objects would be so handy. (And yes I know paper notes and blutack exist, but data can be synced and queried in different ways)
