Unless the user customizes it to call with NOT-SELECTED=nil explicitly:

  (setq display-buffer-alist
        '(((category . xref)
           (display-buffer-use-some-window)
           (some-window . (lambda (_buffer alist)
                            (get-mru-window nil nil nil))))))

PS: after testing I noticed that in your patch
nil needs to be added as a placeholder for empty action:

                  `((xref--display-buffer-in-window)
                    (category . xref)
                    (window . ,xref--original-window)))
                 (t
-                 '((category . xref))))))
+                 '(nil (category . xref))))))
