Are contact groups totally gone for Marshmallow?

I own a Sony XZ with Android 6.0.1 Marshmallow and I just upgraded from a 4.4 KitKat phone. Under Google Contacts you can add each user to one or many groups and these groups were visible under KitKat. I assumed that would stay the same, but it doesn't seem like it. I read that since Lollipop this feature was no longer available. Can anyone support or reject that fact? Is there any way around it? Does anyone know **why** Google removed such a useful feature and then only half (Android support) of it?
