Why couldn't a thermostat that can sense condenser coil temperature be
used to turn on the fan when the coils reach some pre-determined
temperature?


That's exactly what the fan speed modulators do in the links I provided.
The ICM manufactured controls I use, come with a temperature sensor
that's attached to the high pressure line on the condenser coil to
operate the control. ^_^
