Step down approaches have been working just fine for decades. It just takes a real pilot to transition to the final landing phase to make it work properly. Push button pilots running a computer might not find it easy because they are not real pilots, just push button pilots. Blast away.
90 percent of the approaches into San Diego, Ca are step down approaches to the west. It is a major international airport with nobody complaining because they can't authorize an ILS that direction with the obstacles. We need better pilots, not simpler approaches. Get over it.
