I think this kind of haystack recall is going to be extremely valuable to large enterprises with massive volumes of standards/practices/technical documents.
The status quo is that you have employees ingest and internalize this material over years of employment, then have those experienced employees manage large projects by telling the project if they're in compliance with the organization's standards.
A reliable recall system like this isn't just a drop in replacement for new employees, its a drop in replacement for a lot of what makes the expensive employees important: the backwards-and-forwards knowledge of the standards/practices.
