I think the problem is that the tradeoffs already exist. Most users would prefer more usable space or less money to a full history of their data.

You might be making the argument that the usability of immutable data is not there yet, but there are well-established theoretical costs of maintaining full history and I don't think they're within bounds of many real-world use-cases.

If the user doesn't want full history they could configure the database to expunge it with a lifecycle policy, though I think keeping deltas of the changes would make any excess file storage negligible, as most people don't seem to ever get rid of data anyway.

As a guy who's been doing technical stuff of one kind or another since the mid 90's I would say that any analysis that insists that a specific use case has tradeoffs due to lack of memory or processing speed has an inevitable expiration date.
