No, `diff-minor-mode` is intended for use in buffers that need to use
another major mode than `diff-mode`.
[ Like the difference between `outline-mode` and `outline-minor-mode`.  ]

Not sure how important it is in practice: IIRC, I implemented this
because it existed in other people's "diff modes" (when I started
diff-mode I tried to make it a superset of all the diff/patch modes
I could find), rather than because I saw a need for it.
