oncebitten,
You are correct. If you are doing the flanges as one offs you could probably put the flange in a spot where you can get to all 4 bolts. However in production where you do not know what powerplant the end user will install, and/or what set of holes on the mounts ... you cannot put the 4 bolts in position to satisfy everyone. Anything can be engineered for your specific car after the fact...
