I that it should be mentioned that Madara was able to use Kamui just after implanting it, therefor he is a user. But Madara's plan would only require him to use it twice, once to get to the other dimension, steal back his Rinnegan eye, use Kamui again to go back to the real world, and then swap out eyes again. If that happens it should be dealt the same this wiki did with Kakashi using Kubikiribōchō for a very short time period.
