Right, its not the same analogy when you consider the IETF did now 
change "TCP" with a now new IETF STD level change/addition to TCP. 
The problem has alway been that the change was for a last signer trust 
model at the expense of original source policy model which the 
industry clearly desired if TCP was going to be now potentially 
challenged with new TCP signature stamps.
