Races that don't have their own mesh yet share the mesh of other races. Therefore, when their race is released, they will be categorized into the "default" customization of that race, when it came with something like eye tattoos, multiple hair colors, etc.
That might sound confusing, so let me put my idea this way: for races that don't have their own mesh yet, or even races that do, but don't have all of their customization options yet, let them pick what they want their character to have BEFORE it's implemented. This would be a nice way of "planning ahead" for the art department, and it would also make it so people won't have to remake their character they worked so hard on in order to get that one little freckle that they've always wanted on their character.
So let's use Diaboli as an example. Despite sharing the Ynnwn mesh, they still have customizable hair. Therefore, when their race's mesh is released, they -should- have that same hair color they picked, despite the mesh not having been implemented.
Now let's use Hammerwielders as an example. Say they have the choice for a long or short beard; even though their race doesn't have its own mesh yet, they can pick to have either a long or short beard, and when the mesh IS implemented, they have it already and won't have to remake their character in order to get it.
It's hard to word this idea understandably, but if there are any questions I'll try to answer. >.>
