But it does strike me as bizarre that an aircraft can be certified if max (symmetrical) power cannot be used at ALL STAGES OF FLIGHT.
As a non professional pilot, even I know that max power cannot be used at all stages of flight. The fist thing I thought of was an emergency descent after pressurization failure. Come to think of it, any descent with full power would be bad. And not even when descending. With the immense amount of thrust available in these birds it's easy to overspeed. I would dare to say 100% power is very rarely used on a normal flight. Perhaps except at short runway take-off.
