My woke take, as someone who has worked in both a public library and a school library, is that we desperately need both more books that are at a higher reading level but a less mature subject matter, and more books that are at a lower reading level but a more mature subject matter, because 8 year olds who are advanced readers are still 8 year olds and don't want to read about graphic violence and torture, and teens and adults who have learning difficulties or who are just later readers for whatever reason are still teens and adults and don't want to read about Billy the Bunny going to school or whatever the hell.
Shoutout to people in the notes also mentioning people learning the language, I should've mentioned that really, given that I've been stuck reading German picture books myself while learning German.
