This reply supports the second point of the locks being so tied to the current panamax size. Obviously there is balance of current cost to future benefit but this upgrade seems entirely tied to what is relevant today, when we know 20 years from now will be different. If you look at ship sizes they tend to jump a fair bit every ~20 years. There must be another factors like the lake depth encouraging them to restrict to this size. It just seems too short sighted (from my uneducated view), especially when as others have pointed out there are already much larger ships.
