If OS vendor would like to switch to using metadata or tags to organize documents, allowing just two level directory structure could be the first step. Documents in root would end up having no tags at all and the folder name would be used as the tag for those stored in folders. Obviously you could also do this with complex directory structures, but then the tags would become quite long. Metadata/tag based systems don't necessary exclude the complex folder structures as we have seen but having both can make things complicated.
