Wow... easy now, no need for all that capital and bold stuff... we know, you know? :-) That's the whole point about them being customization, innit? Wildhammers are a just another clan of dwarves... but whether you care for their lore or not, I find it hard to believe you'd deny of them having specific looks and a different background.
My point being, where you apparently feel people are trying to shoehorn extra races into the game, I am supportive of another forum member in the belief that new players coming to wow could possibly benefit from being briefly explained why there are differences in the purely aesthetic options they are given when they create a character. :-)
Besides, in the
dev interview with Taliesin & Evitel (from bout 7:22:55, if you want to check) Steve Danuser stated outright that the new customizations are something he was consulted about, to define if they were appropriate, and after discussing the matter they eventually decided that they wanted to give the players the freedom to play their characters as belonging other clans/tribes if they wanted to.
He literally explained their position bringing up the example
"if we give Trolls different skin options that look like other troll tribes besides Darkspears, does that mean we need to make a new starting experiences for them as well...?" And the answer was no - since the drain on the resources to add new starting areas would be huge, they have rather decided to implement those options through the customization of the base races, so not to limit the players due to storyline and resource concerns.
So no,
by Blizzard's own words, when they have decided to add these customization options they have made up their mind about not all Trolls being meant to necessarily be Darkspear, and not all Dwarves being meant to be Bronzebeard, despite of their racial starting area. On the contrary, the players are meant to roleplay their characters as they like them despite of baseline quest text.
And then there's also
Exile's Reach - the new starting area unique to all races... so you do not even necessarily need to hit the original Troll or Dwarf starting zones if you do not want to. :-P
There's obviously a huge chance that since Blizzard does not wish to bother adding starting areas, they also do not wish to have to bother about defining character templates or writing brief descriptions for them, but to think of it, whether people read them or not, there are even short RP tales within the Dungeon Journal, next to the description of the bosses' mechanics, which explain who they are. :-)
To you as well... I am assuming you have not watched the interview I quoted above so I'd recommend you check out what Danuser said. The addition of the skins etc within base customization is EXACTLY about giving players a mean to play all those clans/tribes/subraces without creating redundant allies which would require specific questlines, racials, etc. He LITERALLY advised that people roleplay their characters disregarding the quest text on this matter, and not let anyone tell them who their character can or cannot be on that base. ;-)
They could obviously address it if they wanted, with just a simple 'flag' and text entry. There even was some hype about this in the twitter talks, although possibly wishful thinking.
