The dreaded 'dog bones' fanout... IIRC there are guides stating *exactly* the pattern it should have to maximize available track space... could be a prime candidate for a script. Luckily I eschewed actual BGA layouts for now (since they have a bad reliability reputation in our environment, if you don't do underfill). Also AFAIK you need the somewhat expensive 0.1mm process to do that correctly.
