Regardless, the dismissal of most unorthodox wheel builds is simply due to the fact that there is nothing to be gained by using those build methods. Worse than that, those unorthodox build methods result in weaker wheels due to relying on a component to provide strength in a way that's different than the designers intended.

At least a radially spoked front or rear wheel uses shorter spokes and can reduce the tension differential (for a rear wheel). This all leading/all trailing pattern does neither.
