are we doing CORS? Adding headers? If it is just a one-off fetch, I'd probably long-hand it. If I intended to be fetching from many endpoints, I'd probably write a tiny little abstraction. I'm not exactly keen on loading a 30kb lib (gzipped) so that I can write (maybe) fewer lines for data fetching. Especially considering jQuery's async requests don't conform to the fetch standard. (They reject on 404s)
