I've having a problem understanding the big issues here.
Consider boat diving, carrying the BCD (or BP/W, it makes no difference) on and off the boat each day, and wanting to distribute some of the the weights to higher on the BCD for trim. You can put pockets on the cam band, or just attach weights directly to the cam band. the advantage of the former is how easy it is to remove the weights at the end of the dive day, especially if the weights are borrowed from the boat. The advantage of the latter is no pockets are needed, but the disadvantage is the possible fuss with attaching the weights.
Unless you are trying to achieve a permanent weighting arrangement, what is the problem of pockets?
