Well, that 6. Bc4 in the Schmid Benoni isn't exactly new. There was a Yearbook article on it some years ago which regarded it as a good try for an edge.
The weird thing with 6.Bc4 is it seems to make one of Black's other plans stronger: ...Bg4 to get rid of a minor piece, followed by ...Nbd7, ...a6 and usually ...Ne8-c7, playing for the ...b5 break but also sometimes ...f5.
I have struggled with White against that plan even in its most common version (with White playing Be2), and it looks like White will lose time compared to that with Bc4 and Qxf3 because he probably doesn't want to allow ...Ne5xc4. So I'm skeptical. But I will take a look at what Sielecki has to say about 6.Bc4.
It looks like his line is almost exactly what you would expect based on what you wrote -- White simply gets the bishop pair on f3, loses time retreating, makes normal moves like a4 and Re1 ... But Stockfish seems to give White an edge. He doesn't consider ...f5 in combination with Bxf3 though.
I know what you mean about this line though -- I have never studied it that rigorously or faced it in a slow game but seem to get it in Blitz every couple months, and always feel like I screw it up.
Often playing on auto-pilot, I'll do something like
1 d4 Nf6 2 Nf3 c5 3 d5 g6 4 Nc3 Bg7 5 e4 d6 6 Be2 Bg4 7 Nd2 Bxe2 8 Qxe2 0-0 9 0-0 a6 10 a4 Nbd7 11 a5 Re8 12 Nc4 b5 13 axb6 Nxb6 14 Nxb6 Qxb6
Comp still likes White here and is probably right and I played plans that frequently get recommended in books in Benoni structures (playing Nd2 to avoid ... Bxf3 and get to c4, playing a4-a5 if Black doesn't play b6, etc).
But feels like I'm playing Benko gambit without the extra pawn.
Sometimes instead I've tried Nc4-a5, and trying to go to c6, instead of trading on b6. And during the blitz game I felt like I'm Karpov trying to exploit a weak square (and sometimes the move is good if the tempos work out) but you can also just get the Nc6 in a world of trouble if e7-e6 works for Black and the Nb6 and Nf6 are hitting d5.
Sometime I use the extra tempos to develop the Bc1 but then b2 can be weak, or sometimes I've tried to push e4-e5 quickly but you really need to get the moment right.
So perhaps there's no big rush to move quickly as White, and trading the Bg4 on e2 instead of f3 seems to be nothing special, the Nd2-c4 plan might be more effective in Benoni than Schmidt Benoni.
