Then go the opposite route. South Korea fines companies thousands of dollars every day a vulnerability isn't fixed. Security is one of those areas where negative reinforcement works better than positive reinforcement.
Sure, I'd be fine with that but that's going to have knock-on effects on developers because they're the ones writing the code and therefore the vulnerabilities / bugs. Software engineering would turn into something like civil or aerospace engineering or medicine where where practitioners are required to be certified in various ways, either they or their employers carry liability insurance for bugs they write, and endure onerous processes / audits that their employers and insurers demand of them to reduce the risk of bugs. That I'm fine with too since there's so much crap code being churned out but most software developers probably wouldn't.
