The effective key fulcrum changes more through the stroke 
sitting on a punching than it does on that half dowel, so that 
isn't it. My reason was to be able to stiffen the key, and 
eliminating the half dowels gave me room to add a shoe that 
effectively did that without having to change key buttons. 
I've done it the other way too, adding both a top plate and 
long key buttons, and left the half dowels on. This makes a 
stiffer key, but is a lot more work.
