That's the part I don't get. From the suggested articles explaining CSS Modules I see examples that are easily controlled with simple, vanilla CSS without even the need of a processor. I even see examples where they get more complicated in the SASS part to compare against and yet a simplified CSS pattern (which they even suggest at first) achieves the exact same result. It's almost like those infomercials where the problem is exaggerated to compare against the thing being marketed. I'm interested in these concepts of CSS-in-JS and I really wish the projects wouldn't fall back on such comparisons.
