> The correct way is to use EventSourcing, with each change to an otherwise immutable state being recorded as an Event, including a Delete (both of an Event and the Object).

Another great (and older) approach is adding temporal information do your traditional database, which gives immutability without the eventual consistency headaches that normally comes with event sourcing. Temporal SQL has their own set of challenges of course, but you get to keep 30+ years of relational DB tooling which is a boon. Event sourcing is great, but we shouldn't forget about other tools in our toolbelt as well!
