Hello,

> intended to inform the fundee node that the funder node is definitely sure that the channel funding transaction can never confirm

If the deprecated tx initially sent funds to the fundee via push_msat,
then the fundee may not want to trust the funder on this. One way to
do it trustlessly would be for the funder to attach the actual
deprecated funding tx (not necessarily signed, but still could be big)
to the `funding_cancelled` message, then the fundee would be able to
verify that its inputs have indeed been spent by the overriding tx.

Cheers,

Pierre
