This is because trying to change it could lead to problems when re-submitting the reservation, and it's hard to predict which changes would be allowed. Since if changes aren't allowed, cancellations aren't allowed either. These change and cancel restrictions are under the assumption that advance booking restrictions are setup to prevent last-minute reservations or changes for certain resources.
