Just to be clean, what I was trying to fix actually is something I do in
my configuration file:

#+begin_src: emacs-lisp
(font-lock-add-keywords
 'prog-mode   
 '(("\\<\\(FIXME\\|HACK\\|XXX\\|TODO\\)" 1 font-lock-warning-face prepend)))
#+end_src

This is not something modes do, I think. But doing that have no effect,
because font-lock does not check inheritance, therefore my patches.
