Considering the fact that scss is much more powerful than vanilla css, and Figma showcased double linked variables of the type that are being used in scss code, it would make so much sense to suppport scss out of the box alongside with vanilla css

This is really powerful and would make implementation of DS that much easier.

Otherwise, supporting just CSS introduces the problem of having color names like body-color that just translate to #000 instead of color-neutral-100 for example.

This would make so that devs would have to manually look up hex adresses in the main color definition file to understand what colour variable name “body-color” refers to if they would be using SCSS
