I thought you were overlooking the extremely-improbable case by mistake, rather than overlooking it on principle.
For me, the point of a GLUT is that it is a simulation of consciousness that is not itself conscious, a somewhat different concept from the usual philosophical notion of a zombie, which is supposed to be physically identical to a conscious being, but with the consciousness somehow subtracted. A GLUT is physically different from the thing it simulates, so it’s a different starting point.
