AFAICS the principle difference is that the "canonical" window manager expects you to click on a window to resize or move it. (And, if you chose to size to 1x1 that can be tricky - but not impossible.)

In contrast mir_proving_server the window management currently resizes or moves the active window regardless of where you click. This happens even when you click on another window on another screen.

I'm not sure that the latter behaviour is worth preserving.
