There could be many reasons for not changing protocols running on a 
large scale network.  One of them (an important one) is the cost of 
training supporting engineers and operational personnels.  So it has 
to be a significant improvement of the protocol to-be or really broken 
of existing protocol to warrant such a change, IMO.
