This prioritises accuracy/history of what happened, but this has significant disadvantages and practically no advantages (other than "accuracy of what happened".

There are cases where you really do want an append-only leger, where tampering with history is malicious. -- But, generally, it's preferable to be presented with something tidy.

From some other comment in this thread, I get the impression it's possible to re-present a set of changes in a clean/tidy way? That seems a better way of putting it. "You can still have a clean view into a set of changes while preserving an accurate history of what changed".

What's hard to understand is why you'd be against the idea of tidy communication/presentation of changes in the first place.
