Yeah, indeed, although the numa-split case looks like the most useful
one to me.

According to me, it should. Then, at least right now, moving it would
probably kill its performances because all its memory will be far away,
while right now it's all more "stochastic".
Still, I think it should be done, as if you place a domain in a cpupool
at its creation, I think the case of moving it away from there would be
quite rare.
