Should all alts be able to start at level 60 in WotLK?

Details about the next World of Warcraft expansion, Wrath of the Lich King, are still sparse. But from the initial announcement it appeared as if the new class, Deathknights, would not have to start the game from level 1. Instead they would directly start at a higher level, with 58, 60, or even 70 being mentioned as possibilities. Let's say 60, just to spare me the effort of writing "58, 60, or 70" or "a high level" every time.

Now there are good arguments for and against having new characters start at level 60. The advantage is obviously that if you are mainly interested in the endgame, starting at level 60 saves you about 200 hours of leveling from 1 to 60. The expansion adds little or no content for levels 1 to 60, so the option to skip those will be welcome to some. The disadvantage is that a level 60 character already starts with a large number of spells and abilities, and 51 talent points. Not having gone through the leveling process, players don't get the time to learn these spells, abilities and talents slowly, but have to start learning to swim at the deep end of the pool.

But now lets say we are okay with Blizzard's decision that Deathknights start at level 60. Then why would somebody making a Deathknight alt start at level 60, while somebody making a warrior alt, or an alt of any other class, will still have to level up from 1 to 60? The *option* to start at level 1 has to keep existing, for players new to WoW, or fans of the old world for example. But if we can start level 60 Deathknights, why not give us the option to start level 60 priests or other character classes? As I said, there are good arguments to start all classes at level 1, but if one class gets the option to start at level 60, then why not all of them? The same arguments that speak for allowing Deathknights to start at level 60 should surely be valid for other classes as well!
