Reminds me of MIT's Exokernel- make the lower level interfaces as low-level as possible (while still providing security) and let user-level libraries provide various abstractions suited to different use cases. No file systems, no network protocols, no processes; just a very thin layer that lets userspace implement those if/how it wants to.
