Well even Lawlor likes to use layouts that include more than just north-south shots... or shots that can't be hit from the 'fan base'
Or games like Black Rose which present objectives that are shootable from the italian bottom, they aren't just squared up to those flippers (the target banks).
Or any number of the wild split playfield designs people came up with in the decades prior to the 90s. Playfields have just gotten very conservative... not that it's impossible. Look at how many EM designs or Gottlieb/Premier designs that broke the playfield into different regions with targets not directly hittable from the two main flippers, etc.
