Excellent presentation of the pending alternatives! For all those who feel anxious about these proposed revisions, I think they are just an expected factor of a young technology still in the throes of birthing. I would be concerned if there were not these periodic "upheavals". That would mean that everything has been figured out and further growth unlikely. So, take a deep breath, cover your bets and enjoy the excitement of being witness to the advent of a new era of culture! The new always arrives in the company of risk.
