Removing cmp certainly isn't the most disruptive change of Python 3,
That was almost certainly the ascii to unicode switch for strings. It is still not quite complete in 3.2 but should be pretty well ironed out in 3.3.
but it seems like the one with the least benefit.
Since the set of changes was finite, there *must* be (at least) one with the lowest benefit/cost ratio. The removal of list.sort(cmp) may well be that one. Certainly, reasonable people can disagree as to whether the ratio is above or below 1.0.
If cmp had not been removed, some other change would have been the worst in this respect, and possibly the subject of a thread like this.
