Why is INDEXED_EXTRACTIONS = json the default configuration?

I'm pretty sure this doesn't follow best practices to index every field from every Cisco DNA event?

Additionally, removing that setting creates a separate problem because then the events are ingested as a JSON array which doesn't seem to be easily broken into separate events... Why wouldn't you have the script parse the results into separate JSON events first?
