Having used ES7 async/await through Babel extensively for some highly asynchronous code, I can say that it feels much better than using Promises alone, even better than using ES6 generators + a runner (especially since async/await meshes so well with ES6 classes).
The only fear I have is that the spec might still change, which is not the case for ES6 features. Do you think my fears are unfounded? Because I'd love to use ES7 for my back-end projects where all database interaction, and by extension a large part of my codebase, relies on promises...
