I agree that front wheels are easier, but your statement that "there is no dish involved" is incorrect.
You still have to dish a front wheel as part of the build. The whole idea of dishing is to get the rim centered between the stays and a front wheel has a good chance to be off center. You can't just assume that a front wheel is going to be dished properly. You still have to check it and in most cases you'll need some amount of correction to get it dead on.
