perhaps Tolkein wanted to make it an open ended book, not to make more of the series, but for the readers to imagine what couldve happened afterwards. Example: Rohan attacks Gondor because of land. tolkein wanted to enrich the readers by making them want to think up things that couldve happened and will happen. Theres no such thing as going too far into a book or series.
