This is tantamount to saying "yeah sometimes our airplanes crash, so from now on we'll just make sure we have less passengers ride in the newer models".

Which would be a pretty reasonable thing to say if you had a large portion of the population on a single plane. What this all comes down to is: problems (small or big; stupidly simple or ridiculously complex) will happen. Isolating problems to the smallest number of people possible is the responsible course of action.

That, of course, isn't mutually exclusive with doing better from a software engineering front.
