FWIW, I've noticed you have a large number of lowercase namespaces reserved (see the bottom of this list). A little bit of investigation leads to a guess that an upload of the Prima dist happened to index all of the examples, which had a number of namespaces used. Perhaps you could go in to PAUSE and give up primary maintenance status of the namespaces you don't need?
