While I do this too I understand the above complaint. I think naturally linux should have more of a system similar to what OSX does. I mean I'm constantly switching between OSX and Linux machines but more and more recently I've been at at mac computer while inside a linux system and that is very seemless because it is the GUI that fucks shit up. But now there's so much momentum that I'm not sure they can go back. I think the only way to make this correction is for a big distro like Ubuntu/Pop/Manjaro/Endeavor to switch to a default with alt or super as they windowed operating key but have the option to switch back (should be implemented in the install process and made clear and easy to undo. But without making it the default it'll always stay the other way. (first introduction should be non-default)).

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.
