This problem is not specific to diff-mode.  Like I demonstrated
earlier, xref requires using xref-after-update-hook,
so now it could look like this:

#+begin_src emacs-lisp
(add-hook 'xref-after-update-hook
          (lambda ()
            (setq-local outline-regexp (if (eq xref-file-name-display 'abs)
                                           "/" "[^ 0-9]")
                        outline-default-state 1)
            (outline-minor-mode)
            (outline-apply-default-state)))
#+end_src

> but wondering whether there's a clean way to achieve the same...

Some time ago in another bug report I proposed to add a hook
at the end of 'vc-diff-finish', so it will solve this problem.

PS: Please give me more time to test your patch thoroughly
in various modes.
