Let me discuss this point, because of all the comments here, it is the most interesting to me... But elimination of DM adjudication from the core rules is not distasteful - just an absurd premise, to me.
Henry, I quite agree. However, I see it from a slightly different viewpoint.
The coming of Organised Play in a larger format than just the few tournaments that gave us the "Giants" series and the "Slavelords" series has changed the way WotC must look at D&D.
Beforehand, it was possible for individual DMs to interpret the rules in the way they best saw fit, and because events were one-offs, their differing interpretations were not a huge problem.
Although, it must be said, they were enough of a problem for Gygax to release AD&D with the stated purpose of making a game where interpretation of the rules was more uniform.
With the latter years of 2E, and the rise of the Living Campaigns, the idea of 'global' tournaments came about, and a greater need for DM standardisation.
I must emphasise here that this standardisation should mainly apply to COMBAT, not the other features of what makes a good DM (storytelling, role-playing, etc.)
If someone plays in a tournament and loses their character, then it had better be because of bad luck or bad play, and not a dodgy rule interpretation! The last - if repeated often - will cause the OP scene to become extremely troubled.
D&D does not attempt to define every action, just the more common ones. If a player is innovative enough to come up with something not covered by the rules - more power to him or her! However, by defining - and defining well - the core rules of combat and some of other challenges, the chance of a player being disadvantaged due to a whim of the DM can be minimised.
Is it perfect in reducing the DM's whim? Of course not. I am simply saying what I believe to be rationale behind the more defined rules of 3E and 3.5E.
Cheers!
