No, I don't mean 4eish.If by that you mean 4E D&Dish, then I'd agree. It's pretty ridiculous to claim it's more D&Dish in the classic sense than settings like Greyhawk, Blackmoor or Mystara, though. Kitchen sinking in everything in 3E doesn't offer a one-way ticket to D&D quintessence (in fact, arguably it leads to the opposite).
And your logic makes little sense to me. If anything, older D&D was the kitchen-sink approach. Stuff was thrown in willy-nilly throughout the development of the game for years and years. Eberron, almost uniquely, although surely someone can find an exception that I'm not thinking of, actually decided to take the rules as written, and the various D&Disms that were too iconic to jettison, and pull them together into a framework that made a lot more sense than the prior settings.
Which really made little sense if you gave them much thought. They were pseudo-Medieval Europe, with mythic Greece and Scandinavia, various pulp and science fiction tropes, and a generous side of Tolkien all thrown in, yet somehow having no effect on the existing pseudo-Medieval European framework.
Although I suspect you're using the word D&Dish in a different manner then me. I'm using it to describe Eberron as the first setting really designed around the ideas of iconic D&D. You're using it to evoke nostalgia of classic D&D settings. whether the iconic elements fit well into them or not.
