Thanks Russ, I sometimes forget what great resources you have there.
It says

Vehicles without A/C do not feature Recirculation Control

Whilst I don't fully understand their use of the terminology, that would seem to explain the presence of this as a build option.

This is something I don't understand about modern vehicles, where they say there is no heater tap, it's done by blending. Does that mean the heater core is always hot??
Looking at the diagram, I can see that the flow of ambient (or chilled) air, vs heated, is controlled by a door. So it's conceivable that it is not fully closing.
But looking at the diagram, I also wonder at the radiation of heat. If that heater core is running full-time, that whole box is going to get warm.
Perhaps this is what the dealer was trying to explain? That the core runs all the time (to prevent freezing and/or other issues) and so there is no way to turn it off or completely eliminate 100% of the heat?
