Yes, this should be supported. The "cleanup handler" in the earlier example
got me on the wrong track, that's why I kept insisting this wasn't necessary.

NumPy re-exports, this was confirmed in issue #10181. That's actually
the main reason why I considered re-exporting rather than redirecting
the standard model and built the test suite around it.
