can lorebooks work outside of roleplay chatbots or are they too niche for that

been playing around with lorebooks lately after seeing them come up heaps in SillyTavern discussions, and it got me thinking about whether the pattern has broader uses. the basic idea is pretty solid, structured context that gets injected dynamically based on keyword triggers instead of dumping everything into the prompt at once. for roleplay and character consistency it obviously works well. but I keep wondering if the same approach could help with things like customer service bots or internal knowledge assistants. like instead of a full RAG pipeline, you just build out a lorebook style system where specific topics or entities trigger the right context chunks. seems like it could cut down on hallucinations in long conversations without the overhead of a full vector DB setup. anyone actually tried this outside of the fiction/companion chatbot space?
