I have a couple of cases where I do this - typically I just soft-delete the old record and insert the new one (the trade-off being that you can't use composite keys in this way). If I want a full revision history I add withTrashed() to the query.

I suppose a package that adds a pre-update hook to do this could work?

I believe WordPress stores a row for each of the revisions, and uses a column to specify whether or not each row is a revision or the most current (active) post.

This would be very easy to implement in Laravel with scopes.

I have a project where I need an audit trail of all edits - I have a base model that writes to an audit table with the old/new values json encoded

Note this isn't used for rollbacks etc, but purely to audit who made what changes
