I'm quite sceptical that it can be ever made to work in a useful
way for real hardware (as opposed to an hypervisor para virtual setup
for which this interface is not the right way -- it should be done
in some specific driver instead)
And if it cannot be made to work then it will be a false promise
to the user. They will see it and think it will work, but it will
not.
This means I don't see a real use case for this feature.
