If what Weopons Hot made you nervous, exercise your right of choice and only fly with carriers who don't use 2nd officers/cruise pilots.
French unions always rejected the notion of "cruise pilot" and you can be assured that the guys at the controls in AF447 were checked out satisfactorily against the same technical standards. Also, AF has a policy of not pairing low experienced pilots on the a/c type when scheduling crews.
However, I can't help feeling that the standards are no longer what they used to be.
