Wrong. The PVR graphics (as used by some Intel embedded for example) is
also not in the kernel for the same reason, ditto some sensor and GPS
devices which are useless without a magic proprietary library.

There are lots of reasons for refusing such code

- Legality questions
- Testability
- Security
- Risk of locking us to proprietary interfaces when we can't change the
  user one

and more
