Haven't had a chance to read this, but it would all fit right in for my campaign. The stagnant pseudo medieval setting with no magic outside of adventurers never made sense to me. I don't go to Eberron levels of magi-tech, but interactive illusions? A magical control panel? Pretty par for the course. If it bothers you, it's easy to change the fluff.
So it's a matter of taste and preference. The game hasn't jumped the shark just because it doesn't stick with old school Gygaxian dungeons. There is far worse, more nonsensical imagery in older mods.
