I wrote about how your changes are make diff-mode _not_ analogous.

One might argue that C-c C-a and friends in a file header should apply
all hunks in a file, or perhaps that there should actually be
diff-apply-file commands, etc.
The way n and p worked was not a bug, yet you gratuitously changed them,
and broke auto-refinement. Why do I have to now hit two keys to refine
the first hunk, and one key to refine the second?

It's on by default, so this statement perplexes me.
