As of v. 2.28 the 'Notes On Privileges And Capabilities' text on the /setup_uedit page still has this:

The Delete privilege give the user the ability to erase wiki, tickets, and attachments that have been added by anonymous users. This capability is intended for deletion of spam. The delete capability is only in effect for 24 hours after the item is first posted. The Setup user can delete anything at any time.

which I think has been noted as not relevant anymore.
