The Leaf heat pump is only for cabin temperature.Anything that get's too hot will fail early... yet there are plenty of reliable products out there that survive without heat pumps. Ironically, the Nissan leaf is the first mass produced EV with a heat pump...Nothing to do with owner behavior. Batteries that get too hot tend to fail early. The early Nissan Leaf had lots of early failures and battery degradation in hot climates. Heat pumps give the car much more control of what temperature the battery is at, which can be optimized for either performance or longevity (a warm battery is better for max performance like a drag run).I found an article on this.A lot of the benefit of a heat pump is hidden. It allows complete thermal control over the battery, which also impacts performance and longevity. An EV is just fine without one in most scenarios, but it's still a big benefit.
I have owned and roadtripped 3 BEVs over the last 9 years, and live in a mixed hot/cold climate. Never had a heat pump in any of them, nor missed having one.

I might buy the argument that it increases efficiency, but longevity of a battery? Maybe for someone completely reckless.
