"Done properly" is the key point here. ;) If that's the case, I do agree with you, too, but there are also people who simply rewrite their existing code just for the sake of doing so, transforming it from one state to another one that's different but not really more easily maintainable, easier to understand or showing any other quality that would justify the time they invested in doing it. And there are also bosses with at least somewhat pointy hair that use micromanagement to make *you* do that, even if they are otherwise quite reasonable to deal with. :)
