Yes, below.

Looking at the code of `after-find-file', I think file-local variables will similarly be overruled by the global minor mode.

I ended up implementing what I wanted below by setting defaults for `auto-fill-function', but that's more low-level than intended, obviously.

I'm bcc'ing the bug DB.

(add-hook 'text-mode-hook 'turn-on-word-wrap) ; turns OFF auto-fill

(defvaralias 'auto-fill-mode 'auto-fill-function)  ; kludge

(defun turn-on-word-wrap ()
  "Turn on Word Wrap mode in current buffer."
  (turn-off-auto-fill)
  (turn-on-visual-line-mode))

;; demo

(global-auto-fill-mode 1)  ; set default
(text-mode)

;; result: auto-fill-mode is on, even though it is intended to be off
