Yeah, but you still have to parse the .obj. What the article is doing is .obj -> .json -> WebGL arrays. There isn't really any reason to put the .json intermediary in the middle. Especially since you will only treat it as a blackbox to pass around. JSON is nice as a hand-editable text format. It isn't designed to be fast to parse, or to produce small files.
