Having groups was the most common use case and is not a copy imho. Even all my non-tech friends have wanted groups since day 1 so that they don't have to manually select same set of people to send snaps to. You want to send some snaps just group A, another to group B and so on. It's a no brainer, unlike Instagram stories.
