Borrowers should be able to granularly delete or anonymise their own issuing histories. Possibly we should only remove what the item was, not the entire record of the checkout. For example, if someone had issued 10 books in the past, but didn't want "the three little pigs" to turn up in their history anymore, they should be able to delete this. This borrower could either show a statistic of "10 issues" with titles for 9, or we could remove the record of the issue altogether.
