I'm not saying hotplug will always be niche. I'm saying the approach we're currently taking is. It seems fairly inflexible to hang the whole thing on NUMA nodes. What does the planned kvm support do? Splitting SRAT nodes so that it can do both actual NUMA node distribution and hotplug granuliarity? IIRC I asked a couple times what the long term plan was for this feature and there doesn't seem to be any road map for this thing to become a full solution. Unless I misunderstood, this is more of "let's put out the fire as there already are (or gonna be) machines which can do it" kinda thing, which is fine too. My point is that it doesn't make a lot of sense to change boot sequence invasively to accomodate that.
