Wow, this was really fast. Congrats to the team.
"I'm a bit concerned that you didn't get in touch with us before you started with the work, since tracking the changes would have been easier. FWIW, Martin von Löwis, Alex and me would be those you can ask if you need any further help"
Unless I'm missing something, it seems fairly clear that Vinay Sajip (plus collaborators) did this entirely without the knowledge of the Django core team... or at least some of them!
