That makes sense unless you are in an area with hurricanes. In places with a high probability of a hurricane hit they have started doing framing with the zip sheathing so it looks like a monopoly house, then they add overhangs that can break off in severe wind rather than taking the roof with it.

It's a shame more houses don't get built with ICF, including the roof. Living in an area that gets hurricanes at least every other year I would happily take a smaller house to get something that could stand up to category 4-5 hurricane.
