If it's a StatefulComponent, then it's ok to reuse it so long as it hasn't been initialised. If it's a regular Component or a TagNode, then it's always ok to reuse. If it's a RenderObjectWrapper, then it's ok to reuse so long as it doesn't have a renderObject. To put it another way, this changes how we prevent the following nonsensical situations from arising: - Sync two stateful StatefulComponents together - Sync two RenderObjectWrappers with RenderObjects together When either of those cases happen, we just drop the old one on the ground and use the new one unchanged.
