Because the problem is not the carrousel itself, but the fact that Russia still produces shit-tier propellants that explode at the minimal shock. Unlike western propellants that sometimes won't explode even if it's hit directly, as we already seen videos of drones hitting Leopards and others.

The carrousel is actually a pretty smart design to protect it from hits since they sit deep below the tank, the Karkhov plant design was even better since the propellants sat vertically so when it got hit by top-attack munitions, it would have less of a chance of hitting the propellant, something that they even did it on the T-14 itself.
