In folklore, necromancy has always been most closely tied with speaking with the dead (though in modern fantasy that element of the necromancy does take second place to raising armies of skeletons and zombies), and because of that, I've always felt it should feature much more prominently with necromancers in D&D than it does.
Personally, I think that it should be a wizard spell as well as a cleric one, and be included on the list of necromancer specialist powers as on the Death domain for clerics.
If it comes to that, I think that as it stands the distinction between the Repose and Death domains are a little arbitrary (good death vs. evil death). I think instead the two domains should be titled Death and Undeath, with one domain focusing on death itself and the other domain focusing on zombies, wraiths, and the rest of the undead crew.
