They're moving more and more away from 'Pen-and-Paper-RPG-made-vritual' to some arcade game. If you don't like exploring Dungeons then don't do them, and don't play a fantasy RPG.

In other words, they are taking away more and more content away from people and thereby choice. During e.g. WotLK you could choose to do the Vanilla Dungeons for some genuine FRPG fun, the WotLK ones for loot-hallways, and the TBC ones for an in-between experience.

With Cataclysm, they already destroyed places like Sunken Temple, Wailing Caverns, Deadmines and Shadowfang Keep, and severely reduced the fun in places like BRD , Gnomeregan and SM by turning them in guided tours iso Dungeoneering experiences.

What point is there to exploring and learning etc. a Dungeon now? There is no sense of accomplishment whatsoever anymore, something boring nerf-bait Boss-fights don't make up for.

This is also partially responsible for the lack of 'world feel' in the game (just as btw Gathering Nodes all over the place): learning the game environment has become meaningless, the game is made more and more a stupid collection of boss-fights.

TLDR: if the designers want more 'loot-tunnels', keep them to the newer Dungeons so people can have choices. Stop monkeying with classic content, not everybody has to like every aspect of the game.
