I don't know, I think race matters. I agree that more could have been done, but there is only so much room in a core book.
At the most basic level, your character's race determines the classes at which your character will excel. If I play a Halfling, by examining stat bonuses and other racial features, I know right away that Paladin, Ranger, Rogue, and Warlock are all very good class choices for me. That combination of classes is going to look a little different for each race.
Also note that racial feats make a big difference. A Halfling Paladin and a Human Paladin will play pretty differently based on the racial feats each chooses (or does not choose). And I'm sure the lists will expand as more books are released. But if you want to stick with core only, you've got a pretty solid list as it is.
It's not perfect, but I think they've really moved in the right direction with racial design. We've got a lot more options in the core than we had before, and you can customize your race with feats as little or as much as you like.
