a daydream setting to stop phantoms

personally, i quite like the phantom, but can see how it is a pretty big problem for alot of players. this 'daydream' setting would allow you to stop phantoms spawning in a world, without mojang having to remove them from the game. it would work simularily to mob grieving, and maybe could just register that the player is always sleeping, so the phantom would never attack the player. this way, players that don't like the phantom wouldn't have to worry.
