Its not that big of a deal. It just means you pull the throttles back by hand rather than let the auto-throttles do it. We're doing big power chops at low altitude at SNA for "noise reduction".
You have to alter your scan a bit and take your eyes off the attitude indicator and airspeed to include the engine gauges at a very busy time.
Pilots resent having to jump through the hoops at SNA because it compromises safety for the sake of a handful of rich people, most of whom bought their houses knowing full well there was an airport next door.
