My analogy, which seems to be a poor one judging by the downvotes, is that css is lowest level you can get for layout in browser, so it's inevitable that someone will write something of a higher abstraction to simplify it's usage (discoverable with limited class names), give it a particular purpose (consistent scales), and make it reusable. This is exactly what a library (webserver) is written on top of a language of your choice (java). It's not unreasonable to expect someone to take a similar approach to tailwind and write a similar thing that targets something even more specific such as animations.
