The beefy motors allow a larger fraction of the required braking to go through recuperation, so it should help range as well (assuming somewhat constant efficiency at partial load).
I do wish for a more reasonable EV marketing than the "guilt-free bigger better faster" that we currently see, but technological properties are not in favor of minimalistic EV. The efficiency penalty for overpowered ICE cars was much bigger than that of overpowered EV, but even they never stopped getting more overpowered each iteration.
PS: at least focusing on acceleration goes counter to "just strap on another ton of batteries" tactics. IMHO two tons of technology for transporting one or two persons on land is too much, even if the powersource was rainbows and butterflies.
