It IS kind of nerdy, but presented "within universe," so I don't see where it's that big of a deal.
It's no more nerdy than when a contemporary author publishes a new Sherlock Holmes story and the book states that it is "From the files of John Watson, M.D." and only EDITED by the real author. I'm also a Holmes fan and, while this sort of thing is rather silly, it doesn't really detract from the contents of the book, any more than the "Historian's Notes" detract from the Trek novels.
