Well... No, because the two extreme ends of the filament would have zero feedback signal on it, and only the midpoint would have the full NFB signal on it.
Also, the heating power would increase according to signal level. I've got approx 250mV of NFB. So the filament would see, for heating purposes, total RMS voltage of root-(1.2^2 + 0.25^2) = 1.23V. Not a huge rise above 1.2V, but if signal levels increase, it would become more significant.
