I was poking through obsolete/ the other day and happened upon
ws-mode.el and subsequently the thread

https://lists.gnu.org/archive/html/emacs-devel/2015-05/msg00127.html

The following changes `wordstar-mode' into a minor mode, and also
adds a global minor mode `global-wordstar-mode', which will turn on
wordstar-mode in all buffers except the minibuffer.
