We could add NEWS to auto-mode-alist instead, and that would solve the
issue cleanly for everyone.  That was one of the original
alternatives, but somehow it was forgotten now.

Btw, another issue with emacs-news-mode is that it invokes
outline-minor-mode, which means all the headings-related commands are
now bound to different keys than they were before.  Wouldn't it be
better if emacs-news-mode were a minor mode invoked by Outline
instead?
