How can the end user actually use the biggest new feature: impacts and BMW? As far as I can tell, the issue to actually implement the necessary API changes (IndexSearcher/TopDocs/etc) is still open and unresolved, although there are some interesting ideas on it. This seems like a really big missing piece, without a proper API, the stuff is not really usable. I also can't imagine a situation where the API could be introduced in a followup minor release because it would be too invasive.
