That's why you have 10 workspaces.
Also, when I want to quickly open a terminal on dynamic WMs I have to setup a shortcut for a floating terminal if I don't want it to rearrange everything, while on a static WM I just open a terminal and it'll have no effect on the layout by default.
Ironically I find static window managers to be more comfortable to use the more dynamic my workflow and window arrangements are. i3wm isn't as bad because it doesn't enforce a fixed layout, but it's still more cumbersome once I want to quickly resize or swap around some windows on the screen.
