None of them seems to be aware that "Dux" is not really a good word, because it's the name used by Benito Mussolini for himself. It reads the same as calling this WM "Fuhrer". Not a good name choice. Average look, from the software part, not mature enough compared to other setups such as hyprland or sway.
Dux: "The top (male or female) academic student in a school, or in a year of school; the top student in a specified academic discipline."
I think Mussolini commonly went by "il duce", while dux seems to be going back all the way to ancient Roman times, where it's a noun related to the verb for "to lead", meaning leader, essentially. It and its root gave us "duke", "duct", "produce", among many others.
