> Since OAK-102 NodeStore exposes the branch feature. The initial implementation of TreeImpl on top of this eagerly writes all changes down to the NodeStoreBranch by acquiring a new NodeStateBuilder based on the current NodeState for each change. A better implementation would instead use a NodeStateBuilder per TreeImpl to accumulated the changes and only purge them down to the branch when necessary.
