Qd2 Black has a couple of problems. First of all the Square d6. Secondly the backwards e6. And the third is the trouble extricating the bishop without weakening the c6 field. Probably not losing disadvantage, but still a lot to work with for white. And that still leaves the 18. a3 option. MvH Dan Andersson
