I say it does matter when they are moving the Family size name over the Giant sized name and the Family size winds up being smaller.

Lays Potato chips dropped the Family size name in 2020 as an 8oz bag does not look really family sized.

If you go back to this article it showed off some shrinkflation with some major brands of cereal while not changing the concept name at the top of the box.
