A nav document should be required for all PWPs, just as it is for in EPUB3. Perhaps the logical ordering there could be considered primary, with prev/next allowing the content to function even in harsh environments.

I would expect that a reading environment that couldn't construct UX elements from the nav would not go parse every file. If the currently viewed file has prev/next, it's easy to know where to go next without parsing any other document.
