The only remaining issue I see here is that I think the law may be a bit too heavy handed in how it tries to legislate this system into existence. Trying to tell Bob Hacker writing an OS in his basement what features his code has to include feels a little too authoritarian for my tastes. Probably there are some economic or regulatory levers that could be pulled instead to ensure this system gains mainstream adoption without criminalizing ordinary software development.
Again though, I didn't read the whole bill, just the article, so I could be wrong here on some of the details.
