Is that really a problem? I think you’ve described a valuable signal, and you may have a different threat model in your mind.

If my use case for this device is so sensitive that I’m taking these steps to avoid it being intercepted, any evidence of tampering, even slight, means the device is compromised, /full stop/.

In your scenario when the government hands me three bags of lentils & my device I thank them, walk to the nearest dumpster, and pitch the whole lot in because I have to assume it’s been bugged.
