Re: maybe someone can explain this to me
Just my opinion:
I was watching the History Channel recently and they had a program about metallurgy in the middle ages. Many "experts" believe that we are less proficient in this area than we were hundreds of years ago.
The point is, we don't always go forward. In our high tech culture it is hard to grasp but we regress in some areas.
Probably some wag figured out that they can save an increment by making this change but it is definitely not an improvement
