China Sense - Changes/Differences compared to Sense

After playing around with some RUUs on my E9+, and trying out the HTCCN build, I saw a handful of new features.

App Ops
Auto Start
Brightness Slider in the notification shade
Running app cleaner in the multitask menu
Lockscreen with fewer shortcuts

Now, if I just go to the default.xml in ACC and enable the China Sense flag, then some of these features come back.

I wanted to know where in the device is it determined that certain features are enabled with China Sense.
I went through the majority of the system, but there is nothing glaring obvious that shows any information about it.
