Torque isn't the only consideration, there's also efficiency and acceleration. Transmission aren't a necessity like they are in ICE cars, but they can improve the experience.

For instance the Porsche Taycan:

"Having a multispeed transmission in an EV provides the same benefits that it does in a gasoline-powered car: improved low-speed acceleration and increased efficiency at high velocity by lowering the rotating speed of the power source."

That's also the point to the transmission. A transmission (on the low end) is to enhance acceleration and efficiency (keeping you at an ideal ratio to maintain the speed you're going). Neither of these are issues when you have a flatter torque curve.

Another comment said the efficiency gain on the Taycan is 5% over not having it. Which is about what I would've expected to see, not much for all the added complexity and reliability issues it introduces.
