That'[s why I think we should do this on master, to see if this causes
any problems.

But the ELisp manual says it should:

   -- Variable: window-configuration-change-hook
       A normal hook that is run every time you change the window
       configuration of an existing frame.  This includes splitting or
       deleting windows, changing the sizes of windows, or displaying a
                         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
       different buffer in a window.
