Smart Charging

If Microsoft hasn't already done so, it should explain its reasoning for denying users the option of activating Smart Charging.  Microsoft certainly knows users have important reasons for wanting to control that.  My computer only knows how it's been used.  I know how I will be using it.  So there must be some less-than-obvious reason for restricting that.  Users have control of options that, on the surface, appear much more dangerous than controlling whether battery level charges to 80 percent or 100 percent.
