There's already such a thing with the skill points (and apparently, it's been in there a long time now), but the stat arrows are much smaller and more closely spaced together than the skill buttons, making it much easier for the mouse to slip by a hair and cause a mistake. So it makes even more sense for there to be a stat confirmation box than a skill confirmation dialog box.
