Much of the problem stems from reliability issues. 3X the mechanical equipment leads to 3X the things that can break.

The other main thing is that gensets are fairly awful for switching because they tend to load really slowly. They're designed to only run the prime movers that are necessary for the load required, but in switching, this load varies quite a bit, and it takes time for the other sets to come online when maximum power was needed up front.

Decreased reliability + difficulties switching = pairing with an EMD...
