xmonad neither uses nor cares about virtual root windows; they're the sort
of thing desktop managers use.  Where did you get this idea?

Instead it is rather likely that xmonad is lazy about the notion of screen
focus; in many ways, a workspace with no windows "doesn't exist" even if
it's on a screen, because in practice a workspace is defined by its
windows. In particular, much of the concept of "workspace" is created by
the layoutHook, which usually doesn't do anything if there are no windows.
