There already is a leaner version - ReferenceVertex (and similar Reference* classes). It is just what you are asking for with id and label returned with nothing else. Currently this is the default return value for Gremlin Language Variants - so if you use Gremlin Python, for example, you only get back the id/label for a vertex. We've not changed that for Gremlin string based traversals, which still return Detached*, because it would cause too great a break for too many users at this point. There are a few ways to configure Gremlin Server to return Reference* but the best way is to configured the GraphTraversalSource with HaltedTraverserStrategy and specify that it use the ReferenceFactory for detachment.
