No flips for you!
There's a big difference between moving rules to be player facing and codified and trust. One does not necessarily implicate the other.While this is true, I think it's also equally true that a stated and clear design goal of 3e (and even AD&D, for that matter) to take trust somewhat out of the equation by minimizing the impact of DM judgement and fostering a reliance on rules-as-written. In the D&D-sphere, that's been true since the announcement of AD&D, with maybe the exception of the early runs of D&D (as opposed to AD&D) for a little while after the split, and it's also true in many other non-D&D games as well.
Of course, it's a quixotic and impossible goal, so of course it failed, as you point out. There's lots of ways to abuse the system, and trust is still required. But just because they failed doesn't mean that that isn't where the designer's heads are at.
