No idea about the line that the engines are giving, but from a purely conceptual
perspective it looks compromised. The only question is whether Black can carry
forth this plan. Black could try to trade off the rook for the knight and pawn,
and then direct the queen to g2, but this plan probably fails to work, since if
white places the queen on e2 and brings the king close to the queen, I don't see
how Black makes progress. So yes, I agree it looks very drawish.
