I don’t think there is a problem—node views are created on demand to display nodes, but there is no guarantee that a given node view remains tied to a given node. In fact, nodes shouldn’t be treated as having identity at all—they just describe a given piece of document structure, but their object identity isn’t relevant. A single node object might appear in the document multiple times, for example, and replacing a node with another instance of the same structure will not cause the DOM to change at all.
