Yes with a twist: the French government design system is purposefully reserved for the use of French government websites. I believe that a great design system will be flexible and more akin to user principles first, then implementation interface components (e.g. we need 200 or so components for one of our medical apps), then skinning such as look and feel and themeing.

As one example I'm very keen on coding techniques such headless components as by Bits UI which provides headless components for Svelte. If anyone here wants paid work to code components like these by Bits UI, come work with us. <3
