I love the approach of shadcn and the fact that they use Radix primitives, which have a focus on accessibility. But I wish they would have a pure CSS option without tailwind style classes. It took me some time to translate the classes shadcn uses from tailwind to CSS (which sometimes require more research) and the variables for colors, sizes, etc. into the CSS-to-js system I use (which is stitches - yes, its deprecated, but still the best one I know).

Tailwind is nice for prototyping and simple projects, but often I find that it obscures things too much and when I need more control over the CSS it is too abstract and awkward to use.
