You misunderstand what business this safe manufacturer is in. He's in the business of high-security safes. Any bypass technique he comes up with must be as specific as possible, and defended in every way possible, lest he fail his customers [0] and destroy his reputation (and -thus- his entire business) as a high-security safe manufacturer. So, yes, the technique developed must be limited -as far as is possible- to a single safe (or phone). Anyone who reads HN knows that leaks happen. The more valuable a piece of information, the more likely someone with the ability to snatch it will be targeting it. And -as we should all know by now- it's tremendously difficult to prevent a state-level actor from acquiring data that's not very securely locked away. Again, if you're in the business of providing high-security services to your clients, you are going to ensure that any bypass mechanism you're forced to make is as difficult to create and one-time-use as possible.
