This doesn't seem to match what I sparsely remember about USB HID; At least on my computers I remember Super generating SUPER_L (wayland) or VK_LWIN (w32) - E0 5B scancodes.
At least on Linux you can have bindings CTRL + ESC and SUPER_L be different things if you want.
This does seem to work and is news to me. Windows 11, Leveno laptop. Control+ESC does in fact open the start menu. But none of the other windows key shortcuts work - control+ESC+D did not bring me to desktop, but bookmarked current page in the browser I had open.
