promise-ring [1] is all you need for Node style callbacks. (Bluebird and a few other Promise augmenting libraries also have similar tools, but promise-ring is really all you need.)
Eventually, too, Node and Electron and Cordova and everything else will catch up to the fact that Promises are native in ES2015 and the APIs will eventually migrate.
But the thing about it is toi, async functions also return promises, so not every await require "Promise boilerplate", as you will presumably be using other async functions that produce their own promises.
