:A table might be useful. But in general I agree with Tsavage that there is a tremendous amount of quibbling going on here, which is driven by mutual distrust. We really don't know much right now except that these things are, to the average user, neither extraordinarily helpful nor extraordinarily harmful. (If they were either, it would be quite apparent by now and there wouldn't be anything to argue about). Both sides seem to feel that if they give an inch, the other side will take a mile, and so every millimeter (pardon the switch in measurement systems) needs to be fought over.
