I agree completely, and I guess I should have pointed out that your main point (that programmers take it on themselves to narcissistically fiddle with functioning code) is an excellent one. My comment wasn't meant as a criticism, but as pointing to an unstated assumption-- that the folks fiddling with the code assumed they knew what it was supposed to do-- and that documentation of the actual business requirement ought to be a) present somewhere, and b) consulted before anyone takes it on themselves to mickey with the code.
