Unless blizzard plans to revisit their pre-TBC dungeons, I think it should be fairly safe to drop them all because:

a) You need the quest log space

b) Other than a look-see for kicks or soloing bosses, I doubt you would want to put any real time investment into the old pre-TBC dungeons. And even if you did, you'd need a couple other players to tag along as well, so unlikely.

c) If Blizzard ever plans to update heroic versions of the pre-TBC dungeons, you can be sure there will be new attunements. Even if there aren't, you can easily pick up the original quest(s) again since WOW does not have a upper level cap on quests (unlike City of Heroes which disqualifies a player from taking quests lower than their level even if they never completed it).
