It looks like this is tied to the hardware, so miners should look to avoid a particular manufacturing run of a SKU. Personally, I'm ok with this approach as it's tied to the hardware, and can be researched by everyone ahead of time to avoid "Model X, manufactured from Y to Z dates". Hopefully this can be determined from the SKU + serial number easily by a human reading the serial number. It's not a software driver change nerfing the card remotely, which I would be absolutely against. It appears it could be eventually reverse engineered and bypassed, which I'm also ok with. It's also not immediate e-waste as miners will avoid it anyway, and gamers can just use the card as normal regardless of the manufacturing run -- this isn't hardware that lacks video ports.
