"This is the sort of thing which was done before in a world where there was NUMA"
You sound like NUMA was dead, is this a bit of hyperbole or would really say there is no NUMA anymore. Honest question because I am out if touch.

EPYC chips have multiple levels of NUMA - one across CCDs on the one chip, and another between chips in different motherboard sockets. As a user under Linux you can treat it as if it was simple SMP, but you’ll get quite a bit less performance.
Home PCs don’t do NUMA as much anymore because of the number of cores and threads you can get on one core complex. The technology certainly still exists and is still relevant.
