Maybe it got canned because the pickup dates are not predictable. If I place hold on a book with e.g. two holds on it already by somebody else, the book will be ready in 2 month if each person keeps the book for 1 month. If each person returns it on the spot its basically 2 days. Good luck planning your holidays ard that.
