If it is a warning to the user who produces the patch, and not but a
warning in the patch text for the user who receives it, it is not useful.

Renaming patch needs manual massaging if you want to use GNU patch and
that is not a new issue.  People know that.

The problem is in your example output were that it would break _existing

That's the difference.
