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
I have to say I'm rather not a fan of this idea. Adding messages which do not
result in different node behavior other then waiting for the timeout with
little overhead on the node to simply keep watching for the funding transaction
is a recipe for ending up with a needlessly complex protocol
