IMHO, the NNSP is relatively rarely used and therefore its absence is rarely noticed. Of the 7 fonts that iBooks users can choose form, only one of them, Times New Roman, includes it.
If you don't want to embed a font just to cover all devices, you could mention in your release notes that Times New Roman is the preferred font for books that contain NNSP characters.
As for com.apple.ibooks.display-options.xml, it takes only a minute to add it and doesn't affect epubcheck or other reading apps.
Your Amasis test epub displays boxes, unless Times New Roman is selected.
