We have seen some key-shortening that was a lot worse for
AES-256 due to a worse key-schedule, but they have no real-world impact.
If you know something I missed and there is something worse,
I would appreciate a pointer. 

Real world "absolute security" is somewhere around 80...100 bit of
effective key lenght and that is against known-plaintext, i.e.
the absolute easiest attack possible.
