I was thinking along the same lines as Z. With MuSig2 and pre-sharing of
signature nonces it should stay three rounds and share a similar structure.

Isn't it the case that all previous PTLC adaptor signatures need to be
re-sent for each update_add_ptlc message because the signatures would no
longer be valid once the commit tx changes. I think it's better to put it
in `commitment_signed` if possible. This is what is done with pre-signed
HTLC signatures at the moment anyway.
