Great explanation :) You apparantly are not familiar with the typical positions that emerge from the 7.Be3 Kingsindian. I have played this line numerous times OTB with the white pieces and will give you some insight. There is no favourable way to open the Qeenside for white in this position. You can´t play on the a-file since there is a pawn on a3. If you move that pawn foreward black will happily take on b4 and gain the sqare c5 with huge advantage for black. Interaction between knights?? FYI: The f2 knight never can move since it has to prevent ...g4. If the b5 knight ever goes back to c3 it is not very well placed there at all. The knight is blocked by his own pawns on d5 and e4. There is no better place for the knight than b5 where it at least attacks black weaknesses on d6 and a7, but on the other hand is in the way of his own major pieces.
