The fact of the matter is that no show that's ever been performed onstage makes it back to the professional stage in the same shape it was originally, except maybe the Chorus Line revival.
Every Cole Porter revival interpolates songs of his from other shows. Virtually ever revival changes the book, lyrics, songs, etc, from the original version (as I've said a million times, no too professional productions of Cabaret are ever alike).
The Wizard of Oz wasn't even a stage musical first (at least not THIS version) which makes the argument even weaker. I guess there's the argument to be made that the Wizard of Oz is sacrosanct (but even then, don't most stage productions reinstate "The Jitterbug," which was cut from the movie - and the movie seems to be the standard by which we are supposed to judge this), but it's not like these songs of Lloyd Webber's are going to get stuck into the 1939 movie.
If you're making a moral argument (the authors cannot be consulted and therefore their work can never be altered) fine, but legally, there's no argument. Rights either transfer to someone else or the work becomes public domain. In either case, the authors no longer have any say, because they are dead. Gone where the goblins go.
