The great thing about the new multi-layer icon format in Golden Gate is that it finally separates an icon's foreground from the background. So in theory, it opens the door to returning shape-differentiated icons to MacOS if a future display theme (a successor to the poorly-conceived Clear and Tinted themes) allows the background to be minimized while the foreground is emphasized. What I would love to see, and should now be possible, is a revision of the Clear theme where the squircle is transparent/refractive and the foreground retains its native color.
