Ah, I'd been wondering that myself. If you check the edit history, the majority of the work on that article was in the fist half of 2012, whereas the first other song pages such as magnet were created around May-June. So this is sort of a prototype song page, I believe, before it was established that individual covers were going to be placed on song pages. It would also be fairly difficult to include all kumikyoku, since there are around 10 different versions, so I'm not sure how the formatting would go.
