CYMRU has 7/8 listed as a bogon: http://www.cymru.com/Documents/bogon-dd.html
Their list is more or less authoritative, so I would believe that you should never see traffic from that netblock. This is also consistent with Sprint blackholeing it as a bogon in your original post.
Their list is no more "authoritative" then mine and I suspect they simply did not look into this netblock case before.
I would think IANA is authoritative...(Note that the ARIN whois server will not complain about searches for a prefix, but it won't match anything, you need to search on an IP address.)
