The currently intended allied races are (Horde) Nightborne, Highmountain, Zandalari, Mag'har Orcs, (Alliance) Dark Iron Dwarves, Void Elves, Lightforged Draenai, Kul'tiran Humans.
Don't hate me, but it goes back to classic literary symbolism. The thing about the Alliance is that they're supposed to be noble, righteous, unified. Even their "savage" members, the worgen, still exemplify these traits. The Worgen aren't reveling in their savage new natures; as the intro quests and some of the npc comments support, they actively suppress the feral side of themselves. Not only that, but wolves have a noble imagery and a group mentality/symbolism.
Snakes, on the other hand, evoke the VERY traditional Judeo-Christian imagery of the snake in Eden (even if you aren't religious, the power of religion has permeated our literary history). Snakes are symbolically treacherous and dangerous. This doesn't pair very well the unified front of the Alliance.
Sure, you could try and add them to the Alliance to stir up some conflict, but then you erase the faction identity and distinctiveness. In essence, you really just start re-creating the infighting that is characteristic of the Horde.
I never said they were xenophobic. I only said that the Alliance didn't know better -- i.e., they didn't do their homework. And to be completely honest, I don't think the power structure of the Sethrak would necessarily be easier to relate to. If they didn't do their homework, they're probably making basic assumptions about everything. They probably thought the Blood Trolls were just like the Darkspear and other trolls they had been fighting for years, but of a faction that might be open to peaceful negotiations. And the Blood Trolls were open to negotiations and peaceful relations with the Alliance. . . . it's just that the Alliance really isn't up for human sacrifice.
This actually opens up to my own theory on the matter. Disclaimer: This is a personal theory of mine and as such is purely speculation. There are a LOT of customizations around for Vulpera, and a few more for Sethrak. They're not currently being designed to be released as Allied Races as of the moment because neither race is, plot-wise, suitable for the Alliance (remember, theory). So Blizzard is preparing them in the background, as it were, and will be "sitting" on them for a bit. Then, when later content is released, they might have new races available as part of the plot that WILL be more suitable for the Alliance, and then they release another four races at once.
Right now, everyone is focused entirely upon what we know at this moment. What we don't know is what happens in later patches. Think of something like Broken Shore, but involving the Old Gods (most likely). It might be possible that they've taken the player suggestion and came up with a "redeemed" variant of naga or something like that which have regained their legs, but are still possibly cursed (or something like that). Or maybe a Light-mutated version of faceless. Or Arrakoa. Use your imagination kind of thing.
That's probably the best thing I can think of that would explain why they would add all the additional extras, but not everything, and not come out and say that they're releasing them as an Allied Race, when asked as to what races are going to be allied races.

I'm not going to lie. All of your pictures are adorable. I really want to see Worgen as puppies now and your interpretation of Arrakoa.
