Most attackers aren't nation states, and your security shouldn't rely on obscurity anyways. Having to attack each individual device and having to get specialized equipment to do a highly-skilled attack breaks the vast majority of attack scenarios. This isn't Hollywood. What actually matters to companies is that some 15-year-old with a Flipper Zero can't trivially break your printer ink DRM scheme, and that your debit card can't be cloned without leaving plenty of evidence. Worried about nation-state attacks? Then don't rely solely on sub-$1 hobbyist-level chips for your security!
