Why is it not compatible with the novel-verse?
The novels are read by 1-2% of the viewing audience. Many people who read the novels in MMPB won't ever pick up this high-end collectible. The books are probably aimed at very different demographics.
Making the book compatible with every ENT novel written so far might not be appealing to the creators of this resource, and it would add to the essential research. Perhaps they are canonistas?
