Well, the objection I was raising is that they should control the same
thing. Otherwise we are simply inventing an invasive, high-cost,
nonstandard(*) feature that we have had zero field demand for.

(*) Worse than nonstandard: it actively breaks semantics demanded by
the standard. If I had my druthers we would flat out reject row-level
security filtering of any kind. I don't want us to expend a lot of
effort implementing multiple kinds.
