I've found one single game in my database (CB Mega 2009) so at least it's not a novelty, albeit rare. In my opinion it's not surprising that it's rare because White could reach the position after 8.c4 with a tempo up if he's willing to allow the fianchetto.
Ok, so what does the game tell us? Black pushed through d6-d5 at first opportunity and according to an engine check, it leads to complete equality after 13.exd5.
The game continuation 13.e5 is just crap, leading to a huge advantage for Black.
We also see that it is 12.b3?! that allowed Black to play 12...d5. Alternatives that prevent 12...d5 are 12.Be3 and 12.Nc2. Other than that White has no sensible alternative moves.
After
12.Be3 I considered 12...Ne5. It is totally clear that Black doesn't want to play a passive default Maroczy, because as Discipline already said, the absence of the light-squared bishop favours White. After
12...Ne5 13.b3 a6 14.f4 Black can keep that knight at e5 with
14...Qc7, preparing to retreat it to d7 after White did something against the d-file pin. He'll then bring the knight to c5, putting pressure on e4. I really don't see how Black is any worse here. After
13.Qe2 instead if 13.b3 Black can e.g. stir up a fuss with
14...Nfg4 15.Bf4 Bh4 but I haven't had time to look at the consequences yet.
The other alternative
12.Nc2 looks more sensible. Play might continue
12...a6 13.b3 Rac8 14.Bb2 Qc7 and at least White has reached some kind of default Maroczy now. Black must remember to bring his Nc6 to c5 instead of the Nf6 by means of Nc6-e5-d7-c5. This is for example what Crafty messed up, but Craftly is known to be useless at positional chess.
