I'm not seeing how this is any different from true directories in terms of time and space complexity, as far as rename and path resolution are concerned. Sure, the trie nodes don't have to be implemented as key/value pairs in the data store, but don't they otherwise serve the same purpose in the affected algorithms--pointing to key/value pairs or other directories? Doesn't this still mean that path resolution is O(d) for a path of depth d in the trie, and rename is O(a+b) for two paths of depth a and b?
