Neutral mobs don't become angry or hostile when a goat attacks them

Mobs rammed by goats will no longer retaliate

Well, okay. But it still makes no sense.

And if a neutral mob like zombified piglin sees something like this happening, what is the point of not retaliating if they are rammed by goats?
