Thank you for your contribution.

LGTM, looks like a clear improvement. More generally, I would kind of prefer if each option was either allowed or disallowed with AT_SECURE, but that means we would need a separate one for 'stdout' and 'stderr' only. Let's merge this for now, and think of a more general solution later.
