It’s another slice of Swiss cheese. If the user has a strong enough password or other authentication method through PAM, it might stop or hinder an attacker who might only have a compromised private key, for example. If multiple users have access to the same server and one of them is compromised, the account can be disabled without completely crippling the system.
Using sudo can also help you avoid mistakes (like accidentally rebooting a production server) by restricting which commands are available to the user.






i3 has tabbed windows, and it stands to reason that Sway should have it too.
Hyprland has window groups: https://wiki.hypr.land/Configuring/Dispatchers/#grouped-tabbed-windows
Niri has a feature like that, but a little different since it’s a scrolling tiler. A column that contains two or more windows can be switched to tabbed mode, which displays one window at a time with full height, but you can’t have a tabbed group that is a member of a column, only full tabbed columns.
