This was intended to handle any future use cases where a child is somehow obtained before its parent. As it turns out, all use cases that we've tested so far only require top-down. And the bottom-up capability only leads us to old, abandoned data. Note that Local TA is unaffected; that "tree" is shallow, locally managed, and processed in a manner that doesn't require AIAs. As others have mentioned, bottom-up introduces complexity with (1) stray AIA pointers, and (2) multiple issuers if AIAs must be strict. We have a countermeasure for 1, and currently we aren't strict about 2. But if no bottom-up use cases ever come up, we will default the BBN validator to run top-down only. -Andrew
