Not an oversight, IMHO. I think it's impossible for the document
writers to cover *every* possible usage.

That's why there are usage notes, contributed by users like yourself,
who have found other usages which are valuable (or do not work).

You can always add your own note to the documentation to show how it's
done; in fact I would encourage it.
