I've had a knee-jerk reaction to that job too. But realistically optimizing spark plug changes isn't really important like the old days where you needed to change them every 10k miles or less. It's maybe 2-3 times in the entire life of the car.

Removing the wipers and windshield cowl is generally easy, just takes some extra time. Dealers/mechanics charge for time, not difficulty. So that simple 2hr job can easily be 500-600+. Still something that could be a rewarding Saturday morning project for someone who likes doing DIY type stuff.
