When a pillager from blue team accidentally gets shot by a pillager on red team, they don't start a fight, just like piglins in the same situation, which is a shame, it would be so great if the team command was fleshed out properly(I'm not asking for them to automatically attack each other)

It would be great if there was options for teams, say, making some teams neutral and some hostile or friendly, so party1 can be friendly with party2, while party3 is also friendly to party2 but hostile to party1

Summary again: "Group" based mobs should still get provoked by each other IF they are on different teams
