One in particular I think is fill-nobreak-predicate.  It was a single
function in Emacs 21, later became a hook.  Anyone who followed the
advice of the time to set it to a predicate has had it working fine with
the hook, but taking away the single-function feature of hooks would I
believe break that. :-(
