The move to a framework system where we can all ring what we like and just describe it within an agreed upon nomenclature is a great improvement rather than the legacy Decisions. Having strict rules always seemed quite dated to me - the ringing police after all do not show up if you ring a "banned" performance. But agreeing on names makes communication possible - a good role for a central body.
Jump changes are fun too, but I don't think I agree with the article that allowing them has really led to a revolution. The top performances on BellBoard are of commonly rung non-jump methods. In fact I don't think I've seen a jump method be featured at all. Philip himself doesn't seemed to have published a performance of "Jump" anything since 2013. For many I think it remains an interesting novelty.
