Ahhh feels much better now I have that out my monday morning rant.
That's a very good point. It's not like they couldn't standardize pin configurations. The actual chip is usually no bigger than the size of a head on a matchstick. (Freaky) Case size is normally dominated by the number of pins required. I guess also to, to some extent - thermal dissipation can denote size.
