I think one thing that is important to mention is thst actors can start to self doubt their abilities when they have a different voice. I know for me, I sometimes try to mimic the "accepted voice type" and get frustrated be abuse I just don't sound that way. I don't necessarily want to sound that way, I just think people will feel my singing is ugly or unworthy because I'm not making a similar sound. It's really actually quite scary.
Also, I doubt we will ever hear brash, deep, powerful voices such as Ann Francine, Bea Arthur, Elaine Stritch, Phyllis Diller, and Cleo Laine (especially as she got older). Another set of similar voices we don't hear much are Millicent Martin, Mazz Murray, or Linda Hart. In fact, Linda Hart was under appreciated during her the majority of her career. SHE IS A STAR! I would have loved hear her voice do more villains. Watching her live performance of Velma scared/and enthralled tiny me at the same time. 
You may disagree, but hearing darker skinned women sing in more legit scores is often relagated to white girls, so this contributes to why Audra voice is so "unique".
