View Distance Fade in 1st Person

Right now the 1st person view and cinematic mode has no limitations on how far the user can see. I would personally love the option of being able to set a limit where everything past that point would fade. This would be useful for streaming as a DM to players a 1st person view that matched how far they could see without revealing more than that. I would think the view distance should be infinite by default, but in the settings allow for inputting a number representing how many tiles on the grid the view would reach. It would also be nice if this could be adjusted while in 1st person view, such as with + and - keys.
