I really hope that, in the future, a POD book will be make with all those modules and "fixes", maybe with some insight how the game was made (inside the boundaries of what is possible to say considering the legal terms, like you did on the skill checks document). Some suggested to make a 5e clone, I think that the "clone" already exists and is the original 2014 5e. Having a book with both a "making of" and "update" of the original 5e game can be an interesting book to have near the core 2014 books. That would be really interesting!
