Would be interesting to see if heat pump users get a smaller hit on range indicated when they turn on AC, compared to those without.

All the best

With so many variables in driving style, preferences etc, one will never know. On paper the heat pump is more efficient at heating the cabin, and I think the batteries from the description of the system in the link than a resistive heating system alone in models with standard AC.

With my car with heat pump, pre-heating the car in winter for 20 minutes having charged the car to 80% and still plugged into granny charger, the car still had 80% charge. So granny charger (2kW) was able to supply power needs of heat pump only 1.5kW. Whereas with a loan 1st Edition no heat pump, similar pre-heat only had 75% left, so heat pump certainly requires less power.
Benefit on air conditioning / cooling may be less, as non-heat pump air conditioning unit is basically the same as a heat pump just only able to cool, so only benefit would be higher efficiency of heat pump.
