Others may feel that the Harry Potter series has come to a satisfying conclusion and should not be revisited. They might argue that sequels or additional books have the potential to detract from the existing storyline or overshadow the original narratives. Some readers may prefer to enjoy the series as it currently stands and focus on other ongoing literary universes rather than revisit a concluded one.
In any case, it is entirely up to JK Rowling, and not an externally decidable matter.
