After a considerable amount of back and forth on the Emacs Devel Mailing List, Charles Choi’s Casual Suite has been accepted for inclusion on the NonGnu ELPA repository. If you’re already a Casual user, this makes no substantive difference. You can still get the suite from MELPA as you always have but it will also be available on the NonGnu repository.
Evidently Choi decided to seek NonGnu placement because some folks object to MELPA on philosophical grounds. I’m not sure I understand what the issue is other than MELPA is not officially canonized by the FSF.
To me, that’s just like insisting on a small init.el on religiously grounds. It merely means that you can’t take advantage of all Emacs has to offer. Whatever the FSF’s feeling on the issue, MELPA is, in fact, the premier ELPA repository and almost every package worth having is represented there, and many of them only there.
Still, choices are good and now we have more of them. If, for whatever reason, you have an objection to MELPA, you can still take advantage of the Casual Suite.
