Privileged Helper Application exposes SMC interface

The latest release of this app ships with a Privileged Helper App that exposes an SMC interface [1] that takes caller-specified key names without a whitelist [2]. There are obvious security concerns with not sanity-checking the key names intended to be exposed at the high-security level (helper). To not entirely eliminate this intentional security boundary from Apple, please consider matching the supplied key names against a whitelist. Or, much better yet, do not have any direct SMC exposure, but instead abstract the operations (e.g. expose `setSMCBatteryXYZ` over `setSMCByte` or alike).
