>                      (let ((last-window (buffer-local-value
>                                          'display-buffer-last-window
>                                          (window-buffer))))

This would imply that

- the window showing the buffer from where to read the value of
  'display-buffer-last-window' must be selected at the time
  'display-buffer' is called,

- as a rule, 'display-buffer' cannot set the buffer-local value of
  'display-buffer-last-window' in the window it uses for showing the
  buffer.

Both implications seem harmful to me.
