Oh, it's like cage ( https://github.com/cage-kiosk/cage ) for X11. I was wondering ex. how you'd even move windows around in that little code; the answer is "you don't":)
No it's not. It lets you cycle through active windows with a hotkey, lets you close the current window, and launches dmenu to let you open more applications.
In practice multiple applications get confused, and some don't support -geometry or equivalent.
One specific case I dealt with was Chrome/Chromium that provided all sorts of annoyances until we dropped in a minimal WM (back then it was awesomewm, I didn't know about cage or it didn't exist yet)
In ye olden times, when most X11 applications understood "-geometry" and didn't try to do too much in absence of WM, things worked.
Chromium and possibly others (Chromium is just what I have personally dealt with) was confused about what did it mean to be fullscreen, and various other ideas regarding placing itself on screen.
I did success in making it work for a time, but it was problematic.
