It is probably worth noting that even though iBooks is distributed via the AppStore it is a free download. This may put it in the same category of system apps as Safari and Mail. That is to say an optional install of an OS component.
Sure, but it's a bit annoying that they do use that right for applications distributed through the AppStore (and that their own applications aren't subject to the normal validation process — again within their right).
On the other hand, it may also point to APIs which will become public/documented in the next revision(s) of the SDK.
