Why do you suggest changing anything until you get the answer to this
question? If you don't understand why there are three locations, perhaps
that would be a good initial investigation.
Clearly the short answer is that they reflect three stages of Neil's
thinking on the topic, and I would bet that he had a good reason for
moving the superblock when he did it.
Since you have to support all of them or break existing arrays, and they
all use the same format so there's no saving of code size to mention,
why even bring this up?
