Reducing costs is the wrong incentive. If you look at a modern vendor such as Splunk or CrowdStrike, they have huge estates in AWS. There are huge swaths of repeating data, both within and across tenants. Rather than pointing this out, it is simpler and more effective to charge the customer for this data/usage, and use simple techniques so that it isn't duplicative. Reducing costs would only incentive and increase this asinine usage.
