In this case, the bad routes would not have been believed, and therefore not propagated. The bugs would have been detected much sooner (before shipping), as simple tests would have prevented any routing from occuring. An ounce of prevention is worth a pound of cure. And I agree with Noel, these particular forms of bug (bogus announcement with truncated path, and failure to withdraw) were both more likely to occur with DV style propagation.
