You may be exactly right about these being over engineered as far as 
the compensating pins go, especially in the cars after mid 68 when 
the stub axles got 2mm larger in diameter, but I think the angled 
cutouts are important in keeping the pad wear parallel. Without this 
feature I think the pads will tend to wear wedge-shaped. I admit that 
I don't have a lot of experience with modern calipers, but I think 
the reasoning is sound and all the calipers I am familiar with do 
something along these lines.

As for the impression from the driver's seat, I agree that all of 
these should feel just fine. My point is that there are differences 
that are not perceptable in operation, but which may still be 
important.

To me, leaving some of these features off just smells of cost cutting 
at the expense of quality.
