I think they're replying that way because you seem to miss my point, I didn't think I needed to say that "the operations are the data" explicitly. My confusion was not on what they were doing or why they chose to use a DAG, but why they're presenting it this way and why they weren't using a DAG to begin with. Like I've written task runners in various forms before. They've always been based on DAGs and topological sorting from the beginning. I wouldn't advertise it as such because the choice of model is obvious to me, I'd be more interested in reading about alternatives that provide other benefits.
