Entities in peaceful

In peaceful you could still have every mob their, even normally hostile ones. In peaceful you could make it so that hostile mobs won’t go aggressive and can’t grief your would. For example, endermen, but looking or hitting doesn’t aggravate them. Another example is creepers, they won’t get aggressive, and they won’t blow up unless you detonate them with flint and steel. They could also have a 25% or so less drop rate.
