The line was analyzed and recommended in 2008 by Michiel Wind, see Kaissiber #32, pp. 29-31. His idea 6...e6 7.Nc3! seems indeed critical. You call it "Correspondence Refutation", but I am not aware of older correspondence games.
Naming the variations in the book is surprisingly turning out to be one of the trickiest parts!
I went with the temporary name "Correspondence Refutation" because, contrary to every other variation, the majority of games in this one are correspondence games. The first with g4 and c4 was played in 1997: Teumer-Ruch. The first game with 7.Nc3! was Gazik-Krivoshey, 1998. A strong correspondence game with 7.Nc3! was Ottesen-Corbat, 2007.
However, I don't know of any published analysis on this line at all, to date. Thanks for letting me know, Stefan. I'd be very interested in seeing Wind's analysis, if you have a copy of the article I can check out. The Wind Refutation has a nice ring to it, after all
