Sway/wlroots aren't written in Common Lisp, like StumpWM. The decision to leave window decorations up to the client application rather than the window manager is incomprehensible to me. It just doesn't make any sense so far as I can tell. I don't want to run GNOME or KDE to get redshift behaviour; I want to run a window manager written in Lisp, with a console, emacs & Firefox. Everything else is a distraction from getting work done. I agree that not allowing clients to listen to all keys by default is good; I disagree that not providing a mechanism for the end user to grant such access is a good idea. It's his computer — let him run what he wants.
