And so if there is a need to increase bandwidth there could be an engineering decision to either go with faster links or more links at the existing speed. Faster links has the extra cost of involving more expensive test equipment, more links does not. Strictly speaking perhaps engineering decisions should not consider cost and that's one for the bean counters, but I don't think that's the reality for smaller teams where those two worlds merge.
