With all the respect Ian P., I think you are passing some very sweeping judgments on what is easy or not within mechanical design engineering, as well as the different reasons for this or that solution.
No, he does not. It is exactly the point.
The angles play a very important role for the forces who occur in all the suspension links.
The a-arms including.
For the springs, you want them to see a linear force (with constant ratio) while moving the wheel.
With the very low bodywork, this might get difficult to realize.
Or at least you get to high forces in the strut.
It is not that important whether the rod is pushed or pulled.
You can make a pulled rod lighter but the difference in weight might by minimal.
It is much more important to have the forces attacking in the right way.
