I think that first comment completely misses the point of the article. It's not a matter of whether or not you should or shouldn't make things simpler for the user. It's that you shouldn't view changes as one-time costs - you need to take into account the lifetime maintenance cost of that change you will have to live with. Many times, it is worth the cost because it solves the end-user's problem, that's true. But the point is that we often don't even consider it.
