I can't seem to find any concrete reference specifying the typical diode loss as a resistive loss at all. I was under the impression it's a carrier loss and is not represented by Ohm's Law, and therefore does not have a heat byproduct (other than natural resistive losses in any real-world conductive material). Pedantic as it may be, anyone know for sure?

Not ohms law as applied to resistance, more like a constant voltage drop so power dissipation is voltage drop X forward current = real power dissipated as waste heat wattage. So not like a resistor as voltage drop doesn't increase with increasing current flow, but still real power loss as in Watts = voltage drop X current.
