I still need to find how the main body ECU uses OT+ and OT- but my toyota had a thermistor as well in the circuitry that controlled the AC compressor magnetic clutch. Only reason why I know is because the car had an engine swap and I needed to get the stock HVAC system to kick on the new motor's a/c compressor.
You have proven that the wiring schematic calls out a thermistor in the cabin. Doesn't mean it's used for anything or that it's actually installed, we know it's used for the BRZ climate control, I'm inclined to believe that they use the same wiring for simplicity as the thermistor is likely very cheap compared to the effort of differentiating the two harnesses.

Edit: Not to mention the 10 series has climate control, even less reason to take the thermistor out.
