If you watch the video from a couple of weeks ago where B. Mack goes over all the revisions in the latest FM for the 737 fleet, he explains why we don't run packs and PCA concurrently and according to him it comes directly from Boeing. I don't believe it is going away anytime soon after hearing his explanation, but that is just my opinion.
