I wonder about coming at it from the opposite direction, eg. user installs/creates a new Electrum wallet (or opens their existing one by file or seed), labels 1 of the addresses as "on-chain Zaps", then exports its WIF private key for the Nostr app that will import & do all the derivation work, giving them an npub & p2pkh address that they cross-check against the one in the Electrum wallet.
No need for more recent versions of Electrum (that don't support older computers) if all Electrum is doing is acting as keystore & backup for spending/checking balances.
PGP revocation certs come to mind as well, like if your private key/nsec is compromised (most evident if the balance drops to 0), then you still have the ability to copypaste a bitcoin signed message from Electrum to Nostr first on the compromised account & then the new one you export-import a new private key for.
