I don't mean any disrespect to you or to darktable. That looks like a 
nice tool built on top of LCH. Personally I'd probably never use it, but 
that's a matter of editing style.

But in what universe is that tool more flexible than giving users direct 
control of color through LCH and Luminance blend layers, along with the 
ability to modify Lightness, Hue, Chroma directly using an LCH 
Hue-Chroma tool?

How will that tool allow the user to sample LCH colors to see what 
colors are actually in an image? As an aside, a bunch of RGB values is 
singularly unhelpful information unless the user intends to do a bunch 
of RGB to LCH conversions at the command line.

How will that tool allow the user to choose paint pigments colors from a 
LCH pigment color wheel?
