I'm trying to understand a situation where one would NOT want to use a bidirectional relationship. It seems bidirectional relationships provide more flexibility with data manipulation in the future, and it seems it would be tough to move from a unidirectional to a bidirectional relationship after one has already accumulated a lot of data. So, is there a reason or use case or potential negative outcome in always defaulting to using bidirectional relationships?

Thanks for thoughts!

Best,

Brady
