Move delete item to its own protected method

Problem/Motivation

I'm using the queue_stats module which expects a $item->created property to exist. I would like to move the delete item code

$queue = $this->queueFactory->get($row->get('queue_name'));
$item = (object) ['item_id' => $row->get('item_id')];
$queue->deleteItem($item);

to its own protected deleteItem method on Queue source polugin so I can override it in my source plugin extending it. Since QueueItemDeleteSubscriber is getting the source plugin to check instanceof, maybe it can call the method there as well.
