Install Windows 10, and provide as feedback if you think it is important for Windows to have. So far, no one from what I can see is asking for this, so I don't think many cares.
Also, many don't know what ware level means, and how it is an estimated as the fully charged capacity varies at every charge. And that, even on a new system, the wear level won't be at 0% in many cases, making people assume that their laptop was previously used, or have a faulty battery. This will only make manufactures start lying about the full charge charge capacity, providing false information to the user, and turning the ware level ((full charge capacity / designed capacity) * 100) into a meaningless figure.
