If no matches are found, a false is returned, and you should send a 406 "Not Acceptable" response to the client. If multiple types are supplied, the best match will be returned. If no types are supplied, all acceptable types are returned. Koa's request object includes helpful content negotiation utilities powered by accepts and negotiator.

This may break intended functionality of Koa middleware and Koa itself. Note that using this is not supported by Koa. Use this if you want to write to the raw res object instead of letting Koa handle the response for you.
