Similar milo uses kernel drivers in it's own framework. This has proved to be a major maintenance problem. Milo is nearly a kernel fork.
The design is for the long term to get this incorporated into the kernel, and even if not a small kernel patch should be easier to maintain that a harness for calling kernel drivers.
