There is some concern around a Wagner's attack when using batched updates in MuSig based multi-hop locks. If this was true we'd need to add another round of communication. But I don't see how the attack would work (perhaps I'm misunderstanding it), which is why I added a paragraph explaining why Wagner's attack does not apply.

This text update clarifies my concern, specifically the text "the adversary should not be able to trick the victim into signing a transaction with a different nonce." Thanks!
