What advantage does this offer over composing using standard CSS classes, and maybe even using something like `classnames` to simplify the conditional logic? Feels like tying your project in quite heavily to a library that might become deprecated.
As for it maybe being "deprecated" someday... I don't that's a fair criticism, since any library with a small user base is at risk. This one doesn't have much that can rot, it's not like they are doing transpilations, it's just a thin wrapper over React and CSS modules.
