It doesn't even have to go away. (And on that note, I'm bummed that the conclusion in the article is to do that, especially because everytime this comes up, there's an uproar.) But, jeez. Just tuck it away so futzing with it is an opt-in decision for the 5% of the time that you need to make sure you aren't committing all of your changes. (And on note #2, if a person is doing partially staged changes more often than that, my question is why? What kind of chaotic, stream-of-consciousness style of development leads to that, and is it even producing good results? It doesn't take especially careful planning to not end up in the scenarios where partially committed changes is the answer.)
