The answer won't change my opinion on the matter.
I'd fully expect
the oversighter to either refuse to comment or to lie about it, at
least to me and the general public.
They might refuse to comment, but I very much doubt they would lie.
Why would they? Oversighters are Wikipedians just like the rest of us,
they want the same thing we do - to create a good encyclopedia. I
would expect them to give a simply yes/no answer to whether or not
anything was oversighted on that page - they won't say what was
oversighted, of course.
