Khronkite is another "honorable mention" for KWin tiling and I prefer it over the one mentioned in TFA: https://github.com/esjeon/krohnkite

With KDE+X11 it's trivially easy to change the window manager away from KWin and still get the benefits of suspend/resume, multi-monitor auto-configuration, wifi, system tray, etc, by just setting the KDEWM environment variable in your profile. https://userbase.kde.org/Tutorials/Using_Other_Window_Manage...

But with things moving to Wayland, etc, this simple swap out method isn't possible right now, so I've been keeping tabs and playing with Khronkite and KWin-tiling every so often for when I inevitably swap over to Wayland. It's basically a perfectly serviceable tiling WM OS without having to deal with any of the screen locker, systray, R&R, that Sway et al force you to contend with yourself. Most of the setup is in unbinding system defaults + rebinding window management shortcuts in to better "places".

I still use KDEWM=/usr/bin/i3 equivalent for now.
