Truely said Isaac, mobgriefing should still stay able to be switched off. To provide the possibility to activate desirable "mobgriefing" like villagers planting and harvesting there should be a different setting, maybe "villagergriefing".
This bug should be resolved with another setting: Villager entities should migrate to a different type. So in future we could have their settings controlled by: "villagergriefing=true/false".
