My best guess is that the A320/Veermer block was never in place, due to an oversight or the maybe some special motherboard with A320 that must support Veermer. And some OEMs went ahead and mentioned that. Remember that Veermer is not on all OEM A320 official CPU support list, Renoir is, i think only gigabyte list them. In short, i dont think thats intentional.Then why allow Vermeer for A320 if Renoir was the point all along?
Either that or the fact that B350/X370 are EOL and A320 is not.
The question here would be is how they are actually blocking this? by chipset name or motherboard name? Because due to B350 and X370 going EOL, OEMs got rid of the remaining stock by placing them on A320 boards. Gigabyte A320M-S2H V2 is an example of a A320 board with a B350 chipset that has overcloking enabled for example. Gigabyte list Veermer as supported CPUs on that A320 board with B350 chipset so, to me, they are checking for motherboard name, not chipset ID. Someone should hack the motherboard name string and see what happens.
