Bye bye ICE

The heat pump only helps at modest cold. And in modest cold, the hit to heating is not that bad. In extreme cold, you still need to switch to resistive anyway.

IOW, I doubt that heat pumps are a panacea for all range losses in very cold weather.

Does Tesla have a resistive heaters for the cabin?

Not always. I don't think the MY has resistive, just the HP. A good heat pump will work well below 0ºF.

FWIW, nor is a heat pump in very hot weather a panacea. The range loss will be notable in either extreme. Fortunately, for our climate, it's a good solution.

I'm searching for how low the EV6's works at very low temps. It appears to have logic that turns on resistive heat in a stone cold car to accelerate warmup before switching to HP only operation.

Teslas use the motors to generate resistive heat when needed, by driving the motors off ideal phase. The best part is no part.

Yes, the octoport heatpump design is excellent along with the motor heat scavenging.
