Tree-like hierarchies can be considered as a way to group resources in addition
to flat space. Like in file system, you can have all files in one directory or
you can allocate them in subdirectories in hope to reduce administrative
overhead. It does not mean that notion of sub-directories makes your life
easier automatically. You have plan well and provide semantics of those
subdirectories somewhere else. But it's still much better than storing all
files in one directory.

If you think that the tree-like organization of resource security metadata is
not appropriate/useful/sufficient, then my question is "What are the
alternatives we should look into?"
