Fortunately no one is claiming that it does solve all problems, and I wasn't arguing against that non-claim. My point was, what percentage of supply chain issues (since that 2017 research) would have been mitigated by this policy change?

To be extra clear, I'm not saying "This is a bad policy because it only stops some attacks", I'm just trying to get a sense of scale for how much this will help and how much more work needs to be done.
