It seems like playing it too safe leaves systems vulnerable, and threat actors will inevitably possess ever more similar abilities, and the breaches will happen one way or another, possibly with less or zero accountability if the threat actors pull it off with greater precision. If I were in charge of the law, I probably would begin to incentivize for trusted actors scaling up and aggressively searching for these types of weakness, and privately disclosing them ASAP, so that systems can be patched.
