The Prequels showed how they acted as diplomats, being sent in to peacefully "settle" conflicts. Then they show how they were perverted into generals leading attacks of all things. We see how they related to the Goverment much more specifically, that they had a council, how the council operated. We get glimpses into how they view politics through Obi-Wan and Anakin's conversations in Episode II and III.
I just don't see how you could even say Obi-Wan told us more about them in that hut dialogue.
