That's not on my todo-list for now, -EBUSY :-)

I bump the uvcvideo driver version whenever the userspace API changes. Using 
the kernel version number applications could find out whether the API they 
need is implemented, but detecting API changes would become more difficult. 
That might not be a real issue though, as applications usually don't care.
