That's a good point. At first I was like, NumPy's fame -- owing to the rise of Python in scientific computing and data science circles -- has gone far beyond that of most things ever published in academic journals, so this hardly seems necessary. But I see your point: Nature has always been held in high regard among natural scientists, and though most recently minted natural scientists have at least a passing familiarity with Python, the generations of scientists before them probably don't. Nature at least has enough of a cachet to grab their attention. Plus having a publication in Nature does open doors. Travis Oliphant and some of the already-famous co-authors probably don't need these doors opened, but I'm sure others on that list would benefit.
