To be honest, extra work for processors/renderers that saves work for thousands and thousands of other contributors adding unnecessary tags is, I'm afraid, one of the things we need to live with. If you want to argue for another primitive type in addition to lines and nodes, that's a different matter. But extra tagging isn't going to happen, especially with so many other renderers getting along without it.
