That's a good point. Lacking the light bishop, black is deprived of many
thematic winning sacrifices on h3, making the attack harder. (In tournaments I
used to sacrifice a rook for black's light bishop to defuse the attack!)

However, don't forget that in comparison to a classical KID position, black is
several valuable tempi up, and that the lack of light bishop also weakens
white's defenses of his king, especially the g2 square.
