The thing is, most if not all professional acting contracts include stipulations on looks. If you get cast as the long haired beauty in some up and coming show, you can’t go out & get a buzz cut. Professional acting contracts have very specific stipulations for each job, in theatre & film. Depending on the job, there will be various clauses about things the actor can & can’t do, including weight, hair, etc. The fact that Ellen’s transition was accommodated is not the norm. It’s very far off from standard practices.
