It looks like this touches vcpu initialization, which is pretty core to the functionality of a VM as a whole. Hotplug, on the other hand, while an important feature, is much less commonly used. Given that we're hoping to have an RC5 tomorrow and tag a release next week, I think I'd rather these wait until 4.4.1. -George
