HTTPS/JSON is common place, developers are familiar with debugging problems in that stack. INI or CSV delivered over DNS would be esoteric an unknown to most developers. You might see it as more clunky but I think it's great that the transport and security layer are bundled into something I already work with and know how to debug. I don't think the extra overhead is a concern these days. Most servers can handle that sort of load easily and most clients have not issue with HTTPS/JSON.
