Campy ergo powers are the same way. You have to peel the brake hood back like a banana to get to the bolts.

Given that the internally routed cables go where the screw used to go, I suppose it's the best way to deal with the problem.

Still, I wouldn't trade my ergo powers for a set of down tube shifters. I rode those for like 10 years and while they have their advantages like not having to index the derailleur, I've been spoiled by them.
