Mainly that category-extras doesn't have restricted categories, so most of the categories in data-category cannot be defined with category-extras. This also means that in category-extras many constructions are built from the ground up, instead of being built with a few basic building blocks, because that often requires a restricted category.

But data-category certainly isn't meant as a replacement of category-extras. It is a totally different way of working with CT.
