Smart thermostats are what make them really good. In climates where it gets really cold, you need to have a way to switch over from pumping cold air to pumping hot air to using a secondary heat source.
It wouldn't have to be that smart, or even networked. A z80 or 8008 processor would have been plenty. High end systems could have done it in the 70s, with costs coming down quickly through the 80s.
That's standard for all whole house heat pumps and has been for forever. ( as opposed to the mini split heatpumps where it's a heatpump for one room in a house).
