Ok.Yup. You can download a remote app from the Play Store and control various devices, such as TVs.
Exactly: why installing stuff that it is not needed by everyone and that can be installed from the Play Store? I cannot find any reference to what's exactly installed, though .I'm not sure exactly, but the closest equivalent would probably be OpenGapps nano + Pixel exclusive features. Not that it matters though, as any other gapps can be installed from the Play Store.
