hello. One question. It is possible to have an extension or something that generates a npub and nsec that also generates another public/private keys associated to the same account?. The idea is to have the npub and nsec secure and only use the second key pair and if a mistake is made revoke them and generate a new key pair. I ask ChatGPT first because I'm don't understand cryptography well. The answer was yes, but is complicated experts can do it, so it is like here is the best place to ask this, and if it is practical to implement. 

 While it's not possible today the idea is good and I believe a new standard is being worked on. 

The "recall" of key you mention would need support on protocol level.
