More diplay power modes

[dontcallmedom]

A suggestion made in the WICG to consider more display modes: https://discourse.wicg.io/t/wake-lock-api-support-for-different-display-power-modes/1634/1

(my guess is that it's probably a v2 thing, but I could be wrong)

I think it should be a v2 thing. I'm not sure if any of the major browsers support displaying web pages on the wearable devices such as Android watches, or whether low power modes such as the Ambient Mode on Android are portable between mobile platforms.
Also, the Ambient Mode is different from the usual "screen on" mode because, per Android documentation, the application should adjust its UI specifically for this mode (simplify the layout, remove interactive controls, reduce update frequency etc). So in addition to opting in to be displayed in the Ambient Mode, the web page must receive a message when the system has entered or exited this mode.

It feels like WakeLock is the wrong level to make this differentiation. As @andrey-logvinov mentioned, this is more than just screen on, this is the OS reducing brightness, and changing functionality. As far as the app would be concerned, it would still have a screen lock. Just reduced capabilities.

I don't think it makes sense for it to be in the WakeLock spec, but would also think V2 at minimum
