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.
There's even a few change ringing towers dotted around parts of Africa, Australia, some of Europe. Just few and far between.
But when compared to England, where practically every town can be relied upon to have at least a 6 bell tower where change ringing can happen, it's no comparison.
