FTR, I find the new emacs-news-mode very convenient. Hiding it in
private customizations would remove its convenience.

What about

--8<---------------cut here---------------start------------->8---
Local variables:
coding: utf-8
eval: (or (fboundp 'emacs-news-mode) (defalias 'emacs-news-mode 'outline-mode))
mode: emacs-news
paragraph-separate: "[  ]*$"
end:
--8<---------------cut here---------------end--------------->8---

It requires you to confirm the eval form, but this is the price when you
edit etc/NEWS from master with an older Emacs version.

Best regards, Michael.
