I'm slightly in favor of the kernel implementation because it keeps us
better aligned with VFIO. That means solving problems in one place only
and less reinventing the wheel.
Knowing that a userspace implementation is possible is a plus though.
Maybe that option will become attractive in the future and someone will
develop it. In fact, a userspace implementation may be a cool Google
Summer of Code project idea that I'd like to co-mentor.
