The refinement added to this recent brick oven provides a large work space (when handling baked or roasted products) under the throat of the oven. It harks back to the true Pompeii style ovens (pictured at bottom from my visit to Pompeii, Italy).
Modern-traditional brick ovens like the ones I build also need more-than-adequate fire-proofing from the surroundings. In addition to steel framing and cement board enclosure of the oven volume, I surround the oven with nearly three times the industry standard in refractory insulation. It's an easy equation to see that heat retained is both safe heat and long heat.

I also imagine that the bakery ovens of Pompeii never cooled down until (ironically) after Vesuvius buried the town in 79 CE (Common Era also A.D.).
The bakery oven pictured below is one of the more decorative brick ovens uncovered when Pompeii was excavated.
