I have.  If you do "su -" instead of "su" you expect that to isolate
you from (for instance) hostile clients on the same X session.  I
realize there are ways a determined attacker can get past anything su
can do (by attacking the unprivileged terminal you're typing at, for
instance), but that's not an excuse for su not even *trying*.

That it is documented does not make it not a bug.
