To be exact, both X11 and Wayland window managers decide where windows 
are in last resort.

In the X11 procotol, you can specify an initial window position, and 
move / resize any window, and the window manager may obey, or may not.

With wayland, it is specified that the window manager must not allow the 
client to move a window or specify an initial position. There is no 
protocol for that.
