AnchorEntity a child of an Entity?

Reviewing Apple's AnchorEntity documentation, I see that an AnchorEntity can be a child of an Entity in the RealityKit hierarchy.

Has it always been this way?

In my memory, an AnchorEntity was always just the base element in a Scene.

If this was a change by Apple at some point, has Apple given examples where making an AnchorEntity a child of an Entity lets you do cool things you couldn't do before?

Because AnchorEntity is just a subclass of Entity that conforms to HasAnchoring which requires an AnchoringComponent I think it has always been this way as entities were always nestable.
