RealityKit (iOS & visionOS AR/VR/3D library) makes use of USD. Native apps and games for the Vision Pro will also use USD, alongside their new implementation of Entity Component System (ECS).

Yes, but using .reality files is better for stuff like games in RealityKit. For example it would contain a GPU-ready texture instead of a jpeg (and a lot of other differences), so it's more in-line with how assets are typically loaded in games.

Generally it never makes sense to use interchange formats for a runtime use.

Take the predominant game development format: FBX. It’s used strictly for interchange not runtime.

The use of USD is exactly the same. You’d compile it into a runtime friendly format that benefits your specific runtime.
