I'm sure, that "virtual" logic could be done for bus devices too, if
it's needed. I don't see any reason why that wouldn't be fine.

(The less difference between classes and buses the better. It is wrong
to have two types of subsystems, doing almost the same thing. One
could argue that it could be useful inside the kernel, which it isn't,
I think, but exporting them to userspace was definitely the wrong
thing.)
