I'll add just that, if you put your key in one place, security work only needs to focus on that. If you use more than one nostr app and each signs for you, all it takes is one. The risk squares with the number of apps you put your nsec in. Its best not to train the user to put it in everything they want to mess with. Yours might be perfectly fine (or not), but the next thing they go "it'll be fine" in as a result of getting comfortable with your app might be the one that leaks it and you helped that behavior to become comfortable.
