So that becomes the next question -- will we see an ecosystem of modifications and adapters, to desolder surplus and decommissioned datacenter HBM and put it on some sort of daughterboard with a translator so it can be used in a consumer machine?

Stuff like that already exists for flash memory; I can harvest eMMC chips from ewaste and solder them to cheaply-available boards to make USB flash drives. But there the protocols are the same, there's no firmware work needed...
