I really would want to listen to an Azernaijani Turkic entry one day but unfortunately I also see a high possibilty that they will withdraw in the near future. So far the one and only purpose in their participation was to showcase their power (=providing appealing and successful entries) and, well, they delivered on all accounts. Any further attendance would pose an (in their eyes) unneeded risk. Especially an ethnic entry would march straight to the bottom with that dreadful 'jury', which is already targeting them for political reasons, no matter how good it might be.
Again, I prefer to have them in. I just try to view it from a rational perspective.
