It's going to be a bit surprising in any case.  If I write
foo(1, VARIADIC ARRAY[2, NULL])

then what I'm passing is not a null, and so I'd be surprised if the
function wasn't executed.

I think we should just document this, not make a definitional change
that seems as likely to break applications as fix them.
