And I think that's the key; the rules provide a framework, but the GM and players have to cooperate to make that framework into something more. You would be hard pressed to play the game without making GM calls, and I dare say I've made more GM calls than there are rules at least where the setting is concerned.
It's a fair point asking what others think, but some people get a little attached to their opinion and think it should be treated as fact, so that's always a challenge when asking setting-related rules questions.
