Although if you want a quickie number, having Infofront update the poll of this thread for such would give you a pretty quick result to see if there is division or a clear leaning in one direction or another...
First step might be just to see if there are any objections. For anyone unfamiliar, Chartbuddy would post 3D depth charts once an hour. To get an idea, you can go back about 4 years and see.
If you are talking about Chartbuddy coming back then I feel like just about no one would object. Well before I ever posted on this particular thread I used to drop in just to see CB's latest 3D graph.
As to what has changed since then? Man there are LOTS of new metrics... new parts of the protocol. I am certain there could be some "upgrades".
