Interesting. I guess I'm totally opposite from you; I want there to be very little difference between the races at level 1, but I want strong racial feat support so each race grows differently. I'm all about complexity evolving over character life; its good for new players, and its good for experienced players.
Right now, there is *very* little difference between the races in 4E. Heck, some racial packages are as bad as a crappy paragon class' features. Most racial ability packages break down into 1 heroic-tier quality feat, 1 paragon-tier quality feat, and 1 epic-tier quality feat. Giving players an option to choose a 3rd initial stat bump isn't going to make a dent on that.
So what's the harm in doing it? Isn't it a little silly that Eladrin, a fey race, aren't optimized to become fey pact warlocks? Or that Dwarves aren't optimized to be warlords? Humans are a bit overpowered right now anyway, most players only need to keep a single attack stat high so the second +2 isn't terribly needed.
I think WotC should make racial feats be on par with class feats. Generic feats should be something you fall back on after you've plumbed both the class & race list. And feats that require both a particular class and race should be the most powerful of all. Unfortunately right now racial feats are pretty much bottom-of-the-barrel with only a few exceptions. Stuff like Dwarven Weapon Proficiency, and the Gith blademaster feat should be models for all other racial feats. (weapon finesse...yawn...weapon focus...yawn...weapon proficiency...yawn...paragon defenses...yawn...)
Strong racial feat support is the only way 4E races will ever truly "feel" different imo. A halfling (whatever) should intrinsically "feel" different from a human (whatever). But the way things are right now, they're just small humans....irregardless of whether or not this "third stat" thing happens.
