It's still fully possible, though I'm not clear on whether NUMA-Q supports it. A number of the usual techniques would degenerate to a sort of priority ordering on memory regions. I could imagine it being put to some use to accommodate caches that only cache some regions of physical memory and not others, though it is perhaps a bit far-fetched because few systems like that are still used.
