I know. But I'm imagining that that nsec is a derived nsec from your main one in cold storage (something gzuuus starting working on).
So a normie makes an account at a bunker provider.
The bunker can see that nsec.
But when the normie is ready he can rotate to a new nsec he derived from a mother nsec in cold storage.
Or he can rotate to another nsec from another bunker provider in case of rug pull.
