It Will Be Good A Option To Disable Damage Against Villagers And Iron Golems For Those Players Who Want It.

Thanks for the feature request. I am currently swamped with updating stuff to newer versions so no idea when I will get around to this. If you are on a modern version of Minecraft you can implement similar protections on your own by adding these mobs to the friendlyfire:general_protection entity tag.
