I feel like broaching your wheels and sprockets for hex shaft and using live axles is actually potentially more reliable. At least you dont have to worry about the bolts holding the sprockets to the wheels from loosening. Another thing they could do is have simple bearing blocks machined out of 1/4" thick aluminum to give something a bit more substantial for the bearings to sit in. Although I would agree that if they are using the kit wheels it makes more since to go with dead axle since you would then have to use a keyed hub of some sort.
