Your comment reminds me of the situation of game engines and 3D graphics APIs a few years ago before Vulkan and Metal were released. Too high-level for developers who want control (and understand how the hardware actually works), but too low-level for developers who want to minimize complexity. Now, Vulkan and Metal offer the detailed control for library developers, and everyone else uses some higher-level wrapper. Does it make sense to split the file system in a similar way? I guess the main challenge is avoiding too many competing wrappers.
