I won't deny it can be useful, but it's still not needed. I grew up in Wisconsin (which certainly qualifies as real winters) and you can get by just fine in the winter without 4x4. The biggest problem by far in the winter isn't traction, it's being able to stop when you need to stop. AWD doesn't help with that at all.

The traction control is also significantly better on EVs because you have much quicker response times. I've made it up to ski fields in a RWD Tesla Model 3 with summer tires easily.
