Well I brought it up because I cannot rule out a use/need for them in some path I am not aware of, but by and large they accomplish nothing meaningful. All they do is turn font specific attributes into css, but why? The font is concretely and specifically those very traits -- when you add OpenSans-Bold.ttf, why put a css trait of bold? There's no need, the whole font file can and will only render bold. All these lines of code could ever do of any use is set a trait not dictated by the font file, but what use case would that be?
