I am puzzled by that remark. The authors included a range of opinions and we worked
hard to presents facts (both facts about the published specifications and facts
about observed behaviour of implementations). And the opening paragraph states
"IPv6 routing is entirely based on variable length prefixes (also known as variable
length subnet masks), there is no basic architectural assumption that
n has any particular fixed value."

So I'm afraid that the document is actually stating something about reality,
whether we like it or not.
