Much of the downsides of burying engines in the wing versus in the fuselage (below the H-tail) are irrelevant because the engines are not in a cantilever loaded portion of the structure. A beam has zero bending moment at a free end, and we may treat the fuselage as a long beam with free ends, like a see-saw balanced on a fulcrum in the middle (the wing in this case; we are neglecting the downforce from the horizontal tail). Placing the engines at a far end of the minimizes the bending load they must withstand. Placing engines at a wing root means putting them at the location of maximum bending moment due to the lift acting on the wing.
