We definitely have a big business case (>$1bn/year flows through our bitemporal data). Happy to vouch for you if I can. I work in the insurance industry, and daily face questions like: - What was X's address 2 years ago? - What did our database think X's address was 2 years ago, 3 months ago? It's fundamentally impossible to answer those kinds of queries in a scalable way (parsing application logs is not a scalable way) without bi-temporal data. I'd readily acknowledge that there are some types of data, for which having the capability to answer those queries is overkill. But, in the insurance industry, this kind of introspection is essential from both a compliance and correctness point of view. Personally, if I were an auditor/government regulator for this industry, I would raise a big red flag over any critical data that wasn't bitemporal. I would definitely vouch for its business necessity – so please, keep up your advocacy!! :)
