6...Qxf6 is a useful developing move - many writers caution against bringing the queen out early, but without the b1-knight on the board she doesn't have to worry about losing tempos to Nb1-c3-d5 or Nb1-c3-e4 ideas. Any opening that features a quick ...e5 and ...f5 (looking at you, Latvian Gambit) will likely involve putting the queen on f6 and castling kingside to bring a rook to f8 and then mating White on the f-file.
6...gxf6 has been played by FM Danko Bokan. You get the same pawn structure as in the 6.Qe2 d5 7.Nxf6+ line but White still has the option of putting her queen on a square other than e2.Ruy Lopez
