    Finish this sentence: I would use native promises (instead of bluebird, RSVP) if only they _________.

        probably never. using libs gives consistency across runtimes and allows to patch behavior if necessary.

        when does that end? Do you use userspace arrays? Maps? Avoid new Date()?

        arrays and new maps cannot be expressed as libraries. but such things as fetch can and probably should.

        Map can definitely be expressed as a library.

        well, this just to programmer pragmatism. with browser promises we will still carry polyfills => more complicated witout benifit.

        standard promises have to exist because async APIs have to return something.

        the only promise-d api i know is fetch. and it's redundant. with CBs it was so simple - u use promises in applogic, cb in api calls

        standard callback patterns are not intrinsically simpler than promises and more error prone (ever seen a cb run twice? I have)

        you can still write Promise.all etc in Ember no?

        RSVP.Promise in Ember doesn't resolve as a microtask. So I wonder what timing bugs will be revealed by switching.

        * were cancelable * accepted callbacks & transmuted them to promises to ease transition of legacy code * had well-defined semantics

        promises don't have well-defined semantics?

        and I assume you mean "accepted a node-style, error-first, callback-taking function"?

        yes, though I'd probably feel fine with using a library for this too in some interim period
