What animated example? You mean the youtube video? I didn't see anything compelling in it over CSS. Stuff like "You can now style print media!". The only reason you wouldn't have been able to is because you were using tailwind. This new release is probably an improvement over tailwind v2, but I don't see any improvements over CSS.
It's true that I haven't tried it. And I probably wouldn't, at least until someone can formulate at least a hypothetical advantage.
