I do thing that it's a bit more than replacing the style attribute with the class attribute using a billion classes and css rules that needs to be removed later on, but not much more. You need to know a lot of CSS anyway to understand what tailwind is doing. Raw css is not the perfect solution either, I personnally prefer SCSS but I hope to see better solutions.
