If we're going to entertain conspiracy theories, I favour "A rogue Google agent snuck in to Apple headquarters and edited the file whilst the user was out for lunch". Or perhaps Zergloids. Come on people, we're getting as bad as Slashdot over here!
If we're going to claim this is deliberate, then the same accusation can be levelled at every security bug ever introduce in an edit. This is not evidence, it's just trolling.
Similarly, given how the rest of the changes seemed to be attempts to rename and clean up the API, I expect that it was a junior intern cleaning up code as a whole. It would be more interesting to see the history of the commits, but that's not public (that I know of). It does highlight how we get that data with Google's Android, even though the development and release process is basically the same.
