If you follow my current signer key A and I replace with a different signer key B, you will need to separately start following my signer key B to see its posts on Amethyst in your following timeline.
But if you follow my delegator key X which delegated to signer A and later replaced it with signer key B, then the *Inkan* client will show you all of X's events, both those signed by A and those signed by B, under X's profile.
In the meantime, nothing in the regular Nostr protocol gets broken. From the regular protocol's point of view, A and B are just completely normal Nostr keys. And X is also a normal Nostr key, which will show up in Amethyst as having no events whatsoever. Inkan does not displace or interfere with the current protocol.
To see some key rotations, you can look at the profile of this pubkey:

You can for example pick events from each of May 22, May 28 and June 20. If you click on "View raw event" for each of these, you'll see the different delegatee pubkeys that signed these.
