Would I kick that tank (at least from an easier dungeon)? Probably not, if they weren't useless.
Hadn't thought about the lack of stats and I can see why min/maxers wouldn't want to do this. From a casual's point of view, though, and looking strictly at 5-mans, I don't see the harm. If the group wipes then it's likely not due to the tank dual-wielding, but rather because he didn't use enough AOE. Death & Decay is more than enough to hold aggro on everything, assuming the DPS doesn't use insane AOE to begin with, but in that case a two-hander won't save the day either.
I had the fortune of running three dungeons in a row where the tank was a Death Knight. None of them were dual-wielding, all of them were failing at life to a degree where I, on my Shaman, ended up tanking adds with my elemental, wolves and Shamanistic Rage to prevent a wipe.
My only concern would be the hit cap as I believe it's higher for dual-wielders (unless points are spent in Frost). Missed Death Strikes would result in a loss of self-healing and thus survivability. When my Death Knight tanks, she is responsible for roughly 30% of all healing taken (overhealing not included), so I imagine that would be bad.
In my Death Knight's case, her two-handed weapon was ilvl 316 and she went dual-wield with the 353 maces, which is probably a DPS upgrade even when dual-wielding.
