I think that Apple sees this as not being user hostile. If you want packages installed then you have to use the appstore and in app downloads. This has the advantage of being a consistent experience across all apps. Users do not need to fear in app downloads, or get confused by them they get the same experience every time. Obviously this hurt geeks like us who have no problem using a more exotic system, but in general it favours the bulk of Apples user base. Note that this applies to purchases as well, if you give the app money its always through the same interface. Users see spending money in iOS as being painless and danger free. Do I wish I had more power over my iPad? Sure do, but Apple doesn't care about us, they care about the 90% of users who are less sophisticated then us.
