True, and I don't think I insinuated that it was and epub issue. But, likewise, it also isn't necessary to define a page as the cover, the bibliography, the title page, the toc, the forward, epigraph, acknowledgments, etc, yet all of those options are there as semantics. Following your logic, maybe those options should be removed.
It just seems sort of strange that the developer included so many options as semantics but left that one out. That's all I meant.
