It is not only addressed to the ability to switch back and forth a skin mask, it is about to select a portion of the image that includes skin tones and that only this part is reflected in the scopes.
That's what the highlight button does. It only shows what is in the masked area in both the viewer and the scopes.

Why would I assume it could do that? You mentioned selecting a rectangular area of a clip to check skin tones. How often is that same exact area of the frame representative of skin tones in multiple clips when people can be in different places in different clips or within the same clip? A qualifier selection would make more sense if you wanted to select skin tones between a bunch of clips but skin tones would already have to be pretty close between clips or they won't qualify.
You can see for yourself by adding a bunch of clips to the timeline, going to Color page, clicking the second dot above the Node graph to switch to the node tree for the Timeline, then add a node that does a skin qualifier or window, press the Highlight button, and then scroll through the timeline or jump to clips. This would work do the exact same thing you're suggesting even if the implementation is different.
I don't know why you're rolling your eyes. Your original post didn't really describe the advantage of your idea very well to me. The process you describe is identical to making a mask and turning on highlight, and suggested the advantage would be that you wouldn't have to create a new node to do it. You don't have to create a new node to do it though which is what confused me. I wasn't considering that someone might already have several masks on that node already and that they would also be highlighted which would require someone to make a new node. This thing about it the selection being active for multiple clips was never even hinted at in your original post though.
