I freely admit that if the proper circulator load
exists or if 450 ohm attenuator pads exist, they
will dissipate the reflected power by heating
up the circulator load resistor or the pads.

Considering only the attenuator case, you suggest in such a general
statement that reflected power always increases the dissipation in a real
source that includes an attenuator for the purpose of constraining the
equivalent source impedance.

Such a suggestion is incorrect in the steady state, some loads may increase
the generator's internal dissipation, some may decrease it depending on the
attenuator circuit.
