Callback hell isn't the characteristic of having a callback-based API. It's the code you get when you try to compose it and conditionally fork it without any better abstractions. So promisifying a callback-based API does address it by either letting you use a yield/await abstraction or at the very least promise composition. Wrapping a callback-based API is such a mechanical process that you can wrap entire modules at a time, so I'm not sure what's hellish about that when it gives you promises, something you can actually work with.
