Looks like Microsoft is having another go at releasing update 1809 that includes the flashlight and a bunch of Windows Mixed Reality changes:
Cool.

-
Mixed Reality Flashlight - Open a portal into the real world to find your keyboard, see someone nearby, or take a look at your surroundings without removing your headset! You can turn on Mixed Reality Flashlight from the Start menu, by pressing Windows + Grab on your motion controller, or by saying “Flashlight on/off.” Point your controller in the direction of what you want to see, like using a flashlight in the dark.
