Very true. DC's Shadow Lass also comes to mind.
One of the more interesting twists on this concept was Moondragon. The fact that she was bald instead of a woman with a full head of hair made it easier for her to be rendered in the skimpiest outfits without hardly anyone being offended or seeing it as pervy objectification. In some of Heather's early appearances she was depicted wearing little more than dental floss, gloves, boots and a cape. But I don't recall there ever being any outrage over that.
