Good point. For offline signers, the key rotation story matters a lot: if the invoice key is derived (BIP-32 path m/44/0/0/0/i), you can rotate by incrementing i without re-registering the agent. Only the master xpub needs to be known to the verifier. That way a compromised session key only exposes one index, not the whole identity.
