Deleting Projects Without Notifications to Task Assignees

It would be great if there was an option not to notify task assignees and project owners when a task is sent to the recycle bin.  Periodically, we move completed projects and tasks there that are 180 days old.  We currently use archive folders for completed projects but they still show up in searches and we want the ability to search for items faster without having to look through long lists of similar topics.  Deleting triggers MANY messages in user inboxes that are unnecessary.  Having the option not to notify them would be very helpful in this regard.
