Can't speak for all of them, but my family does at least whenever we can. Our daughter is 5, and we wanted her to know the value of actually sitting at a table together with the TV off and no distractions, just food and each other.
Yes, we always have and always will. Thats our mostly family time as our parents are quite busy so were left to just do what we want. We have ten acres of forest and a pond to explore all day and a great house to watch some movies in
