What if your existing clients might have

(defun paul-callback (computed-data &optional cached)
   ...)

where they make calls to `paul-callback' themselves with the extra 
argument?  It's fair to call this "abstruse" (maybe most/all clients 
just use a lambda), but it might also make you think about providing 
another callback interface.
