Given where the primary force is applied to the crank, this doesn't just sound like a bad ergonomic idea, but poor engineering. Like insisting an I beam needs to be as strong laterally as vertically.
I'm saying that the current design makes them look more aero, but the flat-width does nothing for making them stronger and stiffer where they need to be. It mostly just adds weight.
So, they are bound to flex, especially when you stand on a pedal at 6 o'clock (with all your weight on the pedal), and that I believe helps with the cracking and water-induced galvanic corrosion.
There is some room on the inner (towards the bike) side - they are angled outwards already.
