I think 6979 is a bit of a red herring here. 6979 is about deterministic nonce generation, which is what you do to dodge the problem of having an insecure RNG. But the problem here isn't that the RNG is secure; it's more fundamentally a problem of not understanding what the rules of the nonce are.
But I may be hair-splitting. Like, yeah, they freelanced their own deterministic nonce generation. Either way, I think this code long predates 6979.
