The impact loading on the gear teeth isn't reduced by a final chain reduction or spread out across a chain wrap around the sprocket. Theoretically you can fracture gear teeth easier with this type of loading.
I've never run the calcs for a drive train to what the loading for this is, but I have seen it some of the other gearboxes we've built that don't have a clutch or other slip mechanism in them.
