This is an area of Android that provides enhanced protection for users. While most users won't really need to get this deep when it comes to protections, there are individuals that require these types of protections, like journalists, public figures, and elected officials. So, as you can imagine, having these protections available as an option on Android is a good thing. However, it's important that these things work without any issues, or else you could be looking at additional steps added to your daily routine when it comes to your phone.
