Super is the "Windows" key (or the Command key), it's the "mod key" that can then be set to super or alt/meta or whatever. For the reasons you suggest (WMs often heavily using the super key), I would not want it to be used in the macOS way as I have a few dozen keybinds I'd lose or have to remap then. Stuff like focusing or moving windows or workspaces. Emacs can also make use of the super key, though I don't know if it has anything bound using it by default. The macOS approach is cool and makes some sense, but I wouldn't want it forced on me, and I'm kinda glad I didn't imprint on it.
