I was watching VintageBeef trying to get the loot out of a bastion chest, when he said that he didn't have enough inventory space. He took a shulker box out, opened it to clear his inventory, and the piglins immediately attacked him, even though he opened a shulker box instead of the chest. I think that this makes raiding the bastion harder, because this means that you can only fit 36 types of items in your inventory while near piglins.
