Who makes any of these buffers dedicared?

Try to experiment with an idiom like

      (if prev-buffer
          ;; If a previous buffer exists, try to switch to it.  If that
          ;; fails for whatever reason, try to delete the window.
          (unless (switch-to-prev-buffer window bury-or-kill)
            (window--delete window nil (eq bury-or-kill 'kill)))
        ;; If no previous buffer exists, try to delete the window.  If
        ;; that fails for whatever reason, try to switch to some other
        ;; buffer.
        (unless (window--delete window nil (eq bury-or-kill 'kill))
          (switch-to-prev-buffer window bury-or-kill)))
