It enforces a system invariant at compile-time instead of run-time.

You can't do anything meaningful with this node. As soon as you add it to a
scene graph, you'll get a runtime exception. The fact that you can't extend
`Node` is a system invariant, finding pathological situations in which you
won't get an exception is just a loophole.
