By "solve" do you mean, "actually implement", or do you mean "make
future implementation theoretically possible?"

In other words, would a deployment of SW involve the creation of new
network message for relaying fraud proofs, a specification that SPV
wallet developers can use to validate these messages and so know when to
ignore the highest (but invalid) PoW chain, and the ability to
automatically generate and broadcast these proofs in Bitcoin Core?
