By inspection, it should say something like:

  For graphical file dialogs, any of the special values of MUSTMATCH
  `confirm' and `confirm-after-completion' are treated as equivalent to
  nil.

The idea is that MUSTMATCH = t is still supposed to work.
However, it does not work for me with GTK+ Version 2.18.9 on GNU/Linux
with 23.4 or the current trunk.

I tested with:

(define-key-after menu-bar-help-menu [key]
  '(menu-item "foo" foo))

(defun foo (file)
  (interactive (list (read-file-name "foo: " nil nil t)))
  (setq foo file))

I can happily input a file name that does not exist via the menu-item.
