I mean, those could technically count as a type of memory puzzle.
The first part is in response to complaints over events like "There Is Nothing," where there were answers in previous events, people didn't pay attention to the text or write down information that should have stood out like Sensei's password, and then proceeded to complain when they got stuck because they didn't have the answers they either weren't paying attention to or completely skipped over because they are skipping text.
The second part is due to the fact that this project is now larger than the bible in word count and this count is continually increasing. I have no doubt it will reach or surpass "Remembrance of Things Past" by Marcel Proust, a book with a whopping 9,609,000 words. That's about triple the current latest example he has surpassed, the bible. This game has several more years of development to go, so we have several years to see this happen and each release makes a pretty significant leap.
