The recommended way to implement merchant-calculated callbacks is to
override the class CallbackRules. But if you do that, you don't have access
to private data that you have previously set in the cart. This applies to
both <merchant-private-data> on the order level and
<merchant-private-item-data> on the order line level.
Many merchants need this private data to accurately calculate the tax and
shipping in the callbacks.
