I always thought the branch was an unecessary middleman. Lessening their workload at the branch level may be part of the reason for this in addition to any legal benefits. A few years back the SC was given the power to approve a lower yearly requirement for one year if a pioneer could demonstarte a genuine need and a reasonable guarantee that they could do the regular amount of hours the following service year. This would seem like a natural progression of that empowerment of the elders in this area.
