I don't think that argument "holds water"...especially since all of the new cars use electric locks, at least our '04 does.
I attribute it to an innate love of things mechanical over electrical which is in the blood of the German engineers and their inability to change or admit their's is not the best way to do things. The strength of their designs were always in the steel not in the electrons. They have surrendered, finally, and accepted that electric locks are here to stay.
Having said that I prefer the almost silent operation of the vacuum system to the "clunk - clunk" of the electric locks.
