And you ask what was the point?
I think more than anything, Maytag did this design simply to be different, unique, and to differentiate themselves from every other dishwasher on the market. When they brought out their built-in models in, what 1968 or 1969?, dishwashers were becoming pretty common, not as common as today. Maytag was the very late "newcomer" to the market and I'm sure they wanted to differentiate and be unique to stand out amongs the rest. I loved them and as several on here can attet, loaded right, they held a ton.
