Host `TNode` was passed into `getOrCreateTNode` just so that we can compute weather or not we are a root node. This was needed because `previousOrParentTNode` could have `TNode` from `TView` other then current `TView`. This is confusing mental model. Previous change ensured that `previousOrParentTNode` must always be part of `TView`, which enabled this change to remove the unneeded argument. PR Close #38707
