I've tried following the logic and history of the :group keyword in
easy-mmode.el, and I'm not sure how that's supposed to work any more.

`define-minor-mode' used to document taking a :group keyword, but that's
been removed in:

commit 6e7736ac5f42e2f1b17aacdfb2a60d8bb951d038

The only remaining mention is in this example:

For example, you could write
  (define-minor-mode foo-mode \"If enabled, foo on you!\"
    :lighter \" Foo\" :require \\='foo :global t :group \\='hassle :version \"27.5\"
    ...BODY CODE...)

`define-globalized-minor-mode' does mention it, though, and passes it on
to `define-minor-mode'...  which doesn't use it?

I've added Stefan to the CCs; I'm sure he knows what's going on.
