Sounds like a great feature.  I'd love to see such a thing added to `diff-mode`.

Yes, most of `diff-mode` features currently available are designed to
let you change the diff before you do something with it (such as split
a hunk so as to apply/unapply only one part).
That's somewhat related to the above VSCode feature but it's indeed not
the same.
