Minecraft needs a Neutral game mode!

A new game mode that is the middle ground between Easy and Peaceful! All hostile mobs spawn, and will attack other mobs, but will act neutral towards the player. They will only attack if attacked first. Hunger also drops, but slower, so the player will still need to eat. It would be perfect for players who want to play a Peaceful-type game mode for building and exploration but still be able to beat the game by collecting hostile Mob drops not normally obtainable in Peaceful, with no need to switch difficulties.
