Stems are usually lossless files and have an intended purpose for remixing. Do you stop at instruments and vocals or are we talking 100+ tracks? It strikes me as nontrivial work for very limited purpose. Apple can turn your vocals down so now your exports have to include extra tracks? I don't think that's a good enough sell. The labels do care about this use case.
