I think these nose variations fall into the category of the law of unintended consequences. The FIA tech regs called for the noses to be lower, in a effort to make them look more traditional. But as usual what the rule makers envisioned, and the designers interpretations, ended up being very different.
I remember how clean & elegant the designs of F1 cars in the late eighties-early ninties were. Good lord look at the hideous devices F1 cars have morphed into now.
