Well, if you play with player wish lists and stuff like that I don't think you do need them._Does_ the game need them, though? Maybe yours does, but does mine?
Similar items (weapon/armor crystals) have been a (very) late addition in 3E and I'm still not entirely happy about the way they were balanced. I'm not sure I want them in 4E (yet).
But I'm thinking they would make a great DM tool to hand out specific and evocative treasure while keeping things as flexible as possible

In other words, adding value to the game.
I know nothing of the 3E counterparts, and I refuse to buy the argument "let's skip them in 4E, they were broken in 3E"...
