So make a thread about that, where you can get attention for this issue. 
I promise I won’t be pedantic and I’ll enter the thread to say it’s not important or consider it an action that makes it impossible for other problems to be resolved.

Night Elves, Taurens, Orcs and Blood Elves have received many customization options. The other races also deserve something to be done more towards them.
I can say that at least in this thread and Keori’s thread (Worgen Customization Mega Thread), they are exposed many things that are desirable by worgen players as available to their toons for better characterization.
