Yes, but if you find a bug in development and you are days away from shipping, and you have a solution that fixes the problem but doesn't address the root cause, are you going to delay the whole launch so you can fix it before hand? or are you going to release with the patch, and fix the root cause later?

Now software is different than cars, but I'm gonna say that I'd go for the latter just about every time. Both as a developer, and as a user.
