I agree, but its usage in Emacsen with larger numbers present can be
problematic.

I'm pretty sure that I've written code that's essentially along the
lines of

(when list-of-numbers
  (let ((i most-positive-fixnum))
    (dolist (a list-of-numbers)
      (setq i (min i a)))
    i))

to get the smallest number in a set.  (Not exactly like that, of course,
but using `most-positive-fixnum' as a guard value, knowing that none of
numbers in list-of-numbers can be larger than that guard value.)

So perhaps a warning might be warranted?
