Based on this thread, it doesn't look like the Unity engine supports it yet.

Yup, that doesn't necessarily mean Pantheon will automatically utilize it though. The option is certainly available to them, but in the past, they've said their general disposition toward new tech is to wait and see if/when it makes sense to do so. They aren't ones to quickly jump on board with the latest trends. They need to make sure it will interact well with everything they have going on first.
