A bit more about why the 3rd option is "Put all versions of the book to one page":

If we decide that content differences don't qualify for the book to have a separate article, then even if the book has completely different contents but still has the same (or almost the same) name or parts of the text, it is added to the hub book article.

A bit of "reductio ad absurdum" to show that we either accept the 2nd point and follow the SF to the word or accept the 3rd point and either be inconsistent or make long hub articles for logically different books.
