Why isn't this a pet?

I got Rhea's Last Egg yesterday. (I just about cried at the end of that quest chain. Gorramit.) I put it in the bank next to Gus' First Aid Kit and the Barov Servant Caller. There are a few others like that, too. Just like back in the old days, they're taking up bag space, and for what? Make them vanity pets!

It would need a unique model first, but yeah, this particular item might have been nice as a pet. Quest reward pets are still a few and far in between. Gasp, doing something that's actually a goal with a reward? Imagine it!

I would love to have a little Rheastraza as a pet. (I think that's Rhea's full name, but my dragon lore is a little rusty.) But one of my favourite quest chains, only beaten by Welcome to the Machine in Hillsbrad Foothills.

It would be really nice, but as said before, it would need an unique model :)

On a side note, the badlands after the cataclysm is one of my favorite questing zones! :)

While not at all pet related, the Horde version of Stonetalon Mountains was my favorite Cata change. It was the zone that finally made me respect Garrosh as my leader.
