I think this problem is solved already, see this video about TrackIR from 1:00 https://www.youtube.com/watch?v=_AO0F5sLdVM (it is called motion scaling). Of course people may still get injuries from this if they do it for 40 hours a week...
I think my ideal VR workspace would be one screen directly in front of me, and then as many screens as I want off in the distance.
You'd be able to easily see the screens in the distance and look for updates/etc and just click on it or whatever to pull that screen closer to you if you want to actually read on that screen.
Isn't that stressful on your neck? In the current environment you can also have 20 screens and switch via key-combinations or using the mouse.
