I think you're overcomplicating things a little bit. A better example of this would be like what I did recently, where I needed to change some non-user-accessible values on a device, could not get ahold of the firmware, and the spec sheets were all behind NDA walls. Instead, I opened it up and read the flash directly, thankfully it was unencrypted, and let deepseek pick it apart and give me a script to fuck with various values including the one I wanted to edit.

Basically like using a gameshark/game genie with extra steps.
