The problem is that no one hierarchy fits every org. Sideways relationships that cross hierarchies exist, other exceptions exist. I find directed-graph-based approach in spicedb to be a better primitive than hierarchy with weird exceptions. Directed edges are a much easier way to think about relationships even if they are logically equivalent to hierarchies. https://github.com/authzed/spicedb https://github.com/authzed/spicedb
