sfx2000, I thought I was being specific? If the concern is a worldwide issue, then yes, it should be implemented worldwide.
If it is not, which seems to be the cases I'm talking about, then it shouldn't be implemented worldwide, nor even have to be discussed as to why that is a bad idea for most of the world.
It's not implemented worldwide - it's implemented on devices that are sold in the US. Manufacturers are always free to not sell their non-compliant devices in the US...
