The only reason would be that this feature could be used independently
of virtio-balloon. But this would of course only be the case, if
ballooning is strictly not wanted in a configuration, or the current
balloon driver gets replaced by an alternative solution.

I don't have any strong feelings about this, just wanted to double check.

Thanks,

David
