Otherwise I see not a single real design advantage of the rear mounted engine.
Besides the additional required mounting structure and the weight of the engines fully adding to the moments on the wing box, tail mounted engines usually require T- tails or at least raised HS, further increasing the weight penalty. The other issues like longer fuel lines, unfavourably long forward fuselage or disturbed air entering the engines have already been mentioned.
Therefore I fully agree to your first statement in the quote.
