Struct SupersededKey 

pub struct SupersededKey {
    pub account_id: u64,
    pub key_name: String,
}

How the account to mint for is decided.

AccountChoice::Prompt exists because a picker cannot run before the exchange: listing the accounts needs a session, and re-logging-in to act on the answer would mean a second sign-in (and a second MFA challenge). The callback is invoked mid-exchange instead, on the one session. A key a switch is about to replace, revoked on the same session once its successor exists.
