Most real World EPUB3s include an NCX for fallback purposes. In fact, I know of very few mainstream reading applications that make use of an EPUB3's NAV document (other than displaying it as an html toc). So most EPUB readers that support EPUB3 in ANY capacity would fail that "basic" test. That's exactly why most commercial EPUB3s being sold include an NCX. There's nothing misleading about Marvin's claim in my opinion. If you can read/navigate real-world EPUB3s that are being sold today, then that certainly qualifies as "basic support" in my eyes.
