I think Nostr App notifications when your meta events are updated from another source could be useful.
Profile to detect general changes, but perhaps also lud/zap payment details too.
Maybe notifications for contact list could be noisy - but maybe a toggle.
And for relay 10002 events, it could tell you the changes.
Then if anything unexpected, you select an old event saved locally in app and then republish a new event with the same content.
And if your zap details changed, likely your account is compromised.
