I had a chat [1] with Brian LeRoux (also one of the original authors of the PhoneGap/Cordova project), and I asked him:

“Does [the promise-based API] [2] address the [Cordova] implementability concerns [Cordova project] had with the sync API? [3].”

Brian answered: “yes, the sync api [3] would not be implementable (or, responsibly so) in cordova so this [2] is much better (our native bridge is async).” 

I promised [no pun intended] to bring Brian's feedback to this group, so here it is.

Brian (cc’d) - if you want to elaborate Cordova's position, please feel free to post a mail to the public-device-apis mailing list.

Given this, it appears we now have two implementers, Google and Adobe, with a preference for the promise-based API [2] over the sync API [3].
