[Request] Can we have a functionality that will leave the tracking on after HMDUnmount?

This is especially annoying in development - I have to do something like put a piece of tape on my headset face sensor so it doesn't turn off. Otherwise I have to keep putting it on and off my head when i'm testing something. 

Ideally I'd like for there to be a way to keep the tracking working, and let the screen(s) turn off.
