OUaT may have established that OZ exists in their universe, but at the end of the day it all comes down to licenses and budget.

Disney has probably prohibited OUaT from touching the OZ franchise, due to the new movie. Same thing can be said for the Aladdin franchise, as Disney is adapting the film for Broadway. There is also Giancarlo Esposito's schedule to consider, as his Genie was quite possibly Jafar. The Little Mermaid would require very expensive special effects, and the show probably cannot afford them this season.
