There were regulations that apply to the number of engines of airplanes when flying on routes that have portions too far from a 2-engine plane to fly with one engine inoperative. There were longer distances for as 3 engine planes (L1011 & DC-10) then there were even regs for 4 engine planes. South pole flights 4 engine had to get special exemptions and inspections.

Now ETOPS has drastically increased the times from a suitable airport for 2 engine planes. But not Australia to South Africa and South America still require more than 2 engines.
Now engines are much more reliable and more thrust so B-777, B-787, B-797 are larger than the B-737 type planes.
Then the new Air force one is a B747 variant with engines that have a classified max thrust which I suspect will fly adequately on 2 engines inop.
