No, not at all. This was a bit sloppy.
This patch was rather showing off how I intend to test the previous patch.
The idea came from a talk[1] at oscon which presented refactoring code with
this differential strategy (except that they used it on a larger code base and
collected the diffs between the new and old code for a while in production
instead of just relying on the test suite passing).
