See how trivial it would be to put the delegated sdist generator into the build-backend within the confines of the current PEP? The build-backend could point to a .py in the current directory that implements itself with different tools, or a delegating build backend could parse a separate source-backend out of pyproject.toml for kicks. So why worry?
