... and here you restore them in some completely arbitrary manner. This
can work reasonably iff all windows show different buffers.

`window-state-get' gets you a Lisp object that you can manipulate. For
example, you can replace point positions in some arbitrary way. Doing
the same with an object returned by `current-window-configuration' is
practically impossible.
