I like fetch except its missing xhr basic stuff like cancel and abort, etc. I don't know who makes these standards.

Abort/cancel has recently been added to the spec as AbortSigal (https://developer.mozilla.org/en-US/docs/Web/API/AbortSignal). Currently only supported in Firefox 57 and Edge 16.

The major thing still missing is upload/download progress.

In remembering this issue I had, I made a frankenstein promise return object mimicking fetch's interface called "retch" but didn't publish it. It allowed progress and cancelling. It made me think would be nice to have a promise interface standard class you could inherit from where you could add sugar to it so the chain would remain consistent with your additional functionality. Anyhoo.
