Yeah, right. Nostr doesn't support changing private keys, because that implies changing public keys, and that's a problem for everyone following you. But it could be solved by the separation of knowledge of private keys from a particular person by putting them in a #Trezor device. The person who has the signing device publishes to Nostr. When leave the company passing it to somebody else. It's not an ideal solution, but it might be enough for publishing news on Nostr.
