There definitely should be an API which is hardware independent.
However, the problem is that the hardware is so flexible that an
hardware independent API needs to be necessarily enforce policies
and possibly do complex image processing which is against the kernel
philosophy and belongs to userspace.

As I see it, it is necessary to provide more or less HW-dependent
API to kernel V4L2. What we need is an userspace library abstracting
that to simple HW-independent API. I think that libv4l is a very
good way to do that, since it still provides the V4L2 interface
but can do things in userspace.
