Maybe we should not change it but take this into account for the next generation of the view. Maybe add an item_creation_date to it.
Furthermore, I stumbled upon the fact that a new revision of an item does not trigger an update on the last_modified date of the acs_object associated with the item.
For us the publish_date of the revision is what counts anyway (with regards to project-manager and contacts), so we are fine here, but it might make sense to keep this discrepancy in mind as well or at least educate people about it.
