That is not quite true. At least in Windows one can click onto the color selection of the global Color Wheel, while holding down the Ctrl key. The selected color range stays visible and the rest is presented in B&W.
If you will, the Hue Mask “replaces” the missing picker in the local HSL tool. But you still need this local HSL tool, when changing Saturation and Vibrancy (unfortunately placed here) or Luminance and Uniformity related to these 8 different color range “presets”.
If it’s an ideal solution, I don’t think so, but that’s what we have now.
Just make the most of it.
