Instead, it pushes a much different kind of supremacy: rigid rules, hard-coded planes, a perfectly symmetrical and consistent universe that everyone can learn fairly easily. No deviation, no variation. A place for everything and everything in its place.
Thing is? The "supremacy of narrative tropes" you speak of is both more realistic as a medieval worldview, and capable of holding your "logical, verisimilitudinous take" inside it, because a mechanistic/clockwork universe is a literary trope too, the music of the spheres and such. But a nailed-down mechanistic universal model cannot go back the other way.
I did not say it was where fun went to die. I would never say such a thing. I did say it was where interesting cosmology went to die. Because the Great Wheel is extremely antagonistic to cosmological creativity. The Feywild and Shadowfell are the only innovations it's gotten in something like 40 years. It effectively cannot grow or change or even get all that meaningfully reinterpreted.
