Summary: Actually this won't work and causes even more crashes. For example, if we reload cell 0 and insert at 0, we end up with just a single delete & insert at 0, which causes an inconsistency exception. `IGListApplyUpdatesToCollectionView` already takes care of avoiding multiple reloads of the same `NSIndexPath` by using a `NSMutableSet` when collecting the `reloadDeletePaths`.
