It's simple. Read backwards down the `develop` branch and read off the `feature/whatever` branches. Just because the graph isn't "pretty" doesn't mean it's useless.
In general, I'm starting to dislike "XXX considered harmful" articles. It seems to me like you can spout any opinion under a title of that format and generate lingering doubt, even if the article itself doesn't hold water. Not to generalize, of course--not all "XXX considered harmful" articles are harmful. They generally make at least some good points. I just think the title format feels kind of clickbaity at this point.
That said, kudos to the author for suggesting an alternative rather than just enumerating the shortcomings of GitFlow.
