I did a little testing for a pigmen farm. I found that shooting a pigment from less than 20 blocks away won't even aggro it! Sometimes while punching a zombie piglin from behind slabs it just forgets about you and walks away. Zombie Piglins rarely share their aggro and it seems babies have a larger aggro range but I'm unsure. This happened both on singleplayer and multiplayer worlds. I did not test on my other devices. Z-Piglins are no longer dangerous at all and are hard to farm.
