The (s)RGB color model is not some legacy choice. It is closely tied to how colors are stored, composited, and communicated to physical displays. And this problem seems a bit artificial - how often do you see a linear gradient between colors like the ones shown in the examples? Finally, it is also trivially easy to get a gradient that looks like the "correct" ones presented in this article, by just adding a few additional color stops along the way that are closer to where you want the intermediate values to be.
