I think it still has some value. A few years ago I was building my color palette, and discovered through trial and error that if I keep saturation and luminosity constant, and just change hue to cover the color space, I get a pretty good looking set of colors. I'm not sure if there's science behind it, but it works in practice, at least for me.
