I think using syscalls directly is a worse idea than loading shared libraries, and new kernel features, like ALSA (audio playback), DRM (graphics rendering) and other use libraries instead of documenting syscalls and ioctls. This is better because it allows intercepting and subverting the calls, adding support for features even if the kernel doesn't support it, makes it easier to port code to other OSes, support different architectures (32-bit code on 64-bit kernel), and allows changing kernel interface without breaking anything. So Windows-style approach with system libraries is better in every aspect.
